Lamp blown on 7 month old projection TV

My JVC HD-ILA‘s lamp shattered on Tuesday. It’s had about 400 hours (max, estimated) on it. Fortunately, replacement is covered because the lamp is SUPPOSED to be good for 7000 hours. Also fortunate, if I did have to pay for it, it would be $199 + S&H. No TV except Azureus this weekend unless I figure out how to hack the scrambling on my TiVo or give in and connect the itty-bitty 14" TV.

Hacked and upgraded Hughes HR10-250 (TiVo)

Hughes HR10-250.jpg Well, I finally got my act together after six months at a hard drive company and hacked my HR10-250 (actually, I have two, here’s the manual). Here’s what I have now:

  1. Changed from built-in (noisy) 250GB Western Digital Hard Drive to extremely quiet 500GB DB35 Seagate drive (this is optimized for PVRs).
  2. I installed a NetGear FA120 USB 2.0 Ethernet adapter ($22)
  3. I installed a fresh HR10-250 drive image using Instant Cake ($20)
  4. I installed a PTVnet upgrade ($20)
  5. I installed a "newer" version of HackMan (for TiVoWebPlus)

Then I futzed around with it all day, now I have internet access to my TiVo from anywhere in the world. I’m considering adding a TiVo status in WordPress, but this is a little two Reality TV for me. I’m still running a little short on the features I want, mainly because I haven’t figured out how to disable encryption on this box:

  • Pull programs off the TiVo, convert to MPEG2 (it appears I did not disabled scrambling properly)
  • Stream content off the TiVo (again, it’s the scrambling, I think)
  • Pull content off the old TiVo HDD onto the computer or onto the new TiVo (will be difficult, scrambled using a different key, I think).

I should be able to close these items in a few weeks, but for now, the web access to show lists is simply awesome. For those also interested in doing the same, here’s the correct order (usual rules apply, if you think you might screw up your TiVo and you’re going to void your warranty, you’re right!). Don’t do any of this, ever.

  1. Disconnect all PC hard drives, set CD-ROM on Primary Master IDE to boot. Connect PATA (IDE) TiVo drive (blank) on Secondary Master with jumper set to Master.
  2. Boot the computer using PTVnet (counterintuitive), it’ll ask where everything is (hda = CD-ROM, hdc = TiVo HDD), and then ask if you have an Instant Cake CD.
  3. Go ahead, throw in the Instant Cake CD when asked, it’ll do as told, and about 1.5 hours later, voila.
  4. Switch the disk jumper back to CS (Cable Select).
  5. Insert disk in TiVo (need two Torx to open case = T10, T15), replacing current drive.
  6. Boot TiVo with TV attached. Go through guided setup. When through, go to reset/restart system
  7. Delete and erase everything. This will take 3 hours on a 500GB. Screen should be red "PVRupgrade" TiVo screen during this time.
  8. Go through guided setup again. Go to info page on TiVo, should show correct number of hours (462 SD, 62 HD).
  9. Connect network adapter (it must be 1 of the 3 recommended by PTVupgrade).
  10. Find TiVo’s network address (comes up as PTVupgrade as a name on your DHCP server)
  11. Upgrade Hackman to newest version (ftp, telnet).

Simple, eh? Discerning readers may ask why I have two HR10-250’s. It’s a short story. One died under warranty. They shipped me a new one. I asked if they wanted the old one back. They said no, it was mine. Hence, two.

HDTV Colorado

I’ve been watching the HDTV situation for some time in Colorado, and I must say, I don’t agree with any of the issues that are brought up to stop the supertower for HDTV on Lookout Mountain in Denver. These folks are all ignorant of the science, pushing their ill-founded fears on the rest of us, when if they bother to do some research, they’d actually understand the benefits of the supertower. It’s bothersome to me mostly because these not-in-my-backyard naysayers understand little or distrust the science that’s gone into EMI (no, it doesn’t cause cancer!). As a frequent reader of comp.risks, the source of these fears is well-known (risks you don’t understand = EMI vs. risks you do = driving a car). Maybe if one person in C.A.R.E. (the supertower detracters) would read this blog, I could convert them:

  • EMI has never, ever been shown to cause any health risk. This includes brain cancer (remember those bogus cellphone = brain cancer stories?) Early statistical studies were flawed, but popular thinking has never been “corrected” of this. Raised EMI in certain regions is caused by the superior coverage of the taller antenna. Since raised EMI doesn’t cause health risks (I would live under a power line), this only means better coverage.
  • Moving to digital television will save lives. Emergency services personnel are hampered by poor communications over an analog system with limited bandwidth. The FCC mandate to move to digital is designed to free up this analog bandwidth for the firefighters, EMTs, ambulance and other emergency personnel who will save your life (I had a heart attack, but died because the communications weren’t working). Everyone within the coverage area benefits from this, especially those near the tower where analog broadcasts are causing all the problems.
  • Lookout Mountain will look better. Really. It’s an eyesore from any distance right now. Here’s a picture I took:

lookoutmountain.JPG
Coming from the Bay Area, where I could get close to 20 OTA High Definition stations, I’m very dissappointed that at similar range, I can only get 3 in Denver (PBS, NBC, ABC) of any value.

I happened to catch the trail end of an ad from hdtvcolorado on ABC showing an animation of how the extremely ugly Lookout mountain would look after a good part of the tower farm is replaced by a supertower (6 to 1!). It’s impressively cleaned up, and would actually turn Lookout Mountain into more of a destination rather than an eyesore. Here’s the picture version I found.

To pretend to balance this entry, here’s the website by the people blocking the supertower. For those with a scientific background, pay special attention to the gross misuse of statistics in the bullseye or sharpshooter fallacy (explained here) on this page (misused here). To summarize, you can’t draw the bullseye after you’ve randomly shot up the wall vis-a-vis cancer cases (see great Frontline episode “Currents of Fear” here, nice write-up here).

D-Link DSM-320 and DSM-520 review

DSM-520.jpg

A friend of mine lent me the DSM-320 (it’s coming back soon, Patrick) and I evaluated it to decide to buy the ($229) DSM-520. Both boxes are UPnP AV streaming devices that let you stream audio, video, etc. from a PC.

DSM-320.jpg

Here’s the differences (all in favor of the DSM-520):

  • Supports WPA encryption on wireless
  • Supports high definition component and HDMI outputs
  • Has plug-in on front for USB drive

First impressions:

  • The box is quick and easy to setup, and found Windows Media Connect, NeroHome and D-Link Media Server without problems.
  • Firmware on both is clunky, and has even crashed a few times on the DSM-520 requiring a reboot
  • D-Link Media Server software is poorly implemented, alternatives including the live video transcoding capable NeroHome (my favourite)
  • Few video formats can be read “out-of-the-box”
  • The current firmware strangely can only be set to FF/Rewind OR jump to location. This is most annoying.

After a few months:

Overall, I still really like the DSM-520, and would recommend it to anyone looking for a high-definition streaming video player for a big-screen TV. It’s relatively inexpensive, and works quite well.

  • You can rip a DVD (I use DVDdecrypter) and play it back later. This is great, but several DVDs change audio language abruptly in mid-movie, requiring the rest of the movie be watched on a computer.
  • NeroHome is my preferred media server, supporting many more video formats for live transcoding than the D-Link Media Server
  • Only D-Link Media Server and NeroHome support fast-forward and rewind (Windows Media Connect 2.0 chokes)
  • I intend to buy an Infrant ReadyNAS NV, which will allow me to stream directly off that, without ever having to keep or turn on a computer in the house (supports UPnP AV).
  • I really wish they’d improve FF/Rev, including both jump, and some kind of “jump forward or backwards a few seconds”
  • I would love to see some kind of webbrowser built-in.
  • Pictures are still broken (either stretched to the wrong aspect ratio, or too small). This needs a bug fix desperately from D-Link

Hand-crafted memory containers from RadioShack

pRS1C-2557662w345.jpgchest.jpg

OK, it’s a surprise that RadioShack has the best price this week ($49.99 for 1GB). JJ at work pointed me at this deal. Here’s the part I like, buried in the description:

Ultra Dual Channel DDR Memory modules ship in a beautifully crated mahogany box

Huh? Now I need to order it just to see if it comes in a mahogany box…

Microsoft XBOX360 review

20050515fb896895.jpg

This one is not going to be easy for you XBOX fans, but here goes.

I bought the XBOX360 on eBay for $540 including shipping and handling. I have the premium console (list $399 not incl. tax). A quick check of Walmart last week revealed this is now in stock. This is the 2nd version of the XBOX360, with the “orange” screen of death problems (overheating?) worked out.
I bought an extra wireless controller, remote control, and a copy of Quake4.

First impressions:

Graphics and startup are underwhelming. The original XBOX had so much more of a WOW factor, but mainly because of the signature Halo title that accompanied it. The XBOX360 is possibly the loudest device in my cabinet, requiring significantly more sound-proofing than any other component, including my television.

1 month later:

Beefs:

  1. Stupid thing won’t stream video off my computer. I BOUGHT IT FOR THAT. (Windows Media Connect gives it the ability to stream music or photos only!) I ended up buying a D-Link DSM-520 to do what the XBOX360 won’t. To summarize the problem, XBOX360’s only stream VIDEO off an attached HDD, iPod, or Media Center PC. So you say, why wouldn’t I move my PC to Windows Media Center? Firstly, Windows Vista will have this feature built-in according to the pundits, just a matter of waiting for the release. Secondly, I run Windows XP Professional, Home and Media Center are huge steps down from this full featured OS.
  2. Games suck and are slow. Quake4 is clearly a bad port onto the console, and graphics are average, and occasionally jerky. Shame on them. On the other hand this is the first time I’ve heard anyone swear in a video game.
  3. Must…… release……….. Halo………… 3.
  4. Can’t download and play, or in fact, download and do anything (need to stay on the download screen or your download is fried).
  5. Can’t surf the net. This would be nice.
  6. No HDMI. And they call themselves high-definition.

Things I like:

  1. It’s kind of a cool, well-designed box
  2. Wireless controllers are awesome.
  3. Plays classic XBOX games like HALO2 quite well, in high-definition widescreen.

What I would buy now:

My XBOX360 is for sale. I really like the DSM-520, and can wait for Halo3 and the HD-DVD add-on drive for the XBOX360. The DSM-520 is really good at what it does! See my review on that in upcoming posts. The XBOX360 is just not what I wanted or needed. I suppose if I had a terabyte of storage on a noisy Media Center PC in another room, this would be an awesome solution for me, but right now it bites.

JVC HD-61Z786 HD-ILA projection television review

HD-61Z786.jpg
Well, I bought the television in August 2005, so I figured it was time for me to write a review. I bought it for $3100 USD from Ultimate Electronics in Boulder, CO. Interestingly enough, I had to talk my wife OUT of buying the 70″ model of the same television (given living room size, you’ll have to forgive me, but 70″ is JUST TOO BIG.
First impressions:

This TV is bright, and the colors are fantastic and bright. The 720p three-chip LCOS is spectacular, and my four high-def sources are well-served by the TV. For reference, my high-definition sources (all dutifully set to 720p, regardless of source image) are:

  1. Hughes HR10-250 High Definition DirecTiVo
  2. NeuNeo HVD108 High Definition (upsampling) DVD player
  3. D-Link DSM-520
  4. Microsoft XBOX360

I’ve also tested the other sources:

  1. Laptop computer (SONY Vaio VGN-T350P) with VGA output
  2. Internal ATSC tuner on the JVC

6 months later:

Well, I still really enjoy the TV, but here’s some of my beefs.

  1. It’s loud, I put sound-absorbent panels on the wall to dampen the fan noise. It still bothers me, and sets up resonances on the cabinet from time to time which can only be solved by “hitting the TV”.
  2. Only 1 HDMI input (heck, I have 2, soon 3 HDMI sources, what am I supposed to do? I’m thinking of buying a multi-HDMI input receiver to do the switching, but REALLY!)
  3. Input switching is ponderously slow. I mean seconds slow. I think discrete codes and a Pronto Neo universal remote will solve this, but for now, ugh.
  4. Scaling options for different source aspect ratios are non-existent! My Panasonic plasma could do all kind of anamorphic scales to put a 4:3 image on a 16:9 screen. This doesn’t do any of them. I really miss this, and this REALLY takes from it’s ability to be a suitable HTPC monitor (it can’t even accept a 720p on the VGA input!).
  5. HDMI input claims not to accept DVI signals (from computers). I don’t even know if this is true.
  6. Only 2 component inputs (yes, with 4 sources, I use HDMI, and use receiver to switch 2 high-definition inputs to get to 3 component inputs and 1 HDMI)
  7. Low-definition content looks terrible. I’m not even sure anyone can do this right except for Faroudja (not even Genesis!). This is the model that supposedly has an improved scaling engine, but I see no evidence of this.

Here’s what’s good:

  1. There ain’t no color wheel. I find wheel noise even more compelling that the fan noise on this unit.
  2. Colors are still great, bright. Even with direct sunlight on the screen (a common problem in Boulder) the screen still works.
  3. Sharpness on high-definition inputs is spectacular.
  4. It works at altitude (I live at 7400 ft)
  5. It’s really thin, much thinner than comparable DLP units and LCD units.
  6. It’s not washed out like the SHARP I was considering in the same period.

What would I buy today:

Honestly, I like the TV a lot. That being said, the new round of 65″+ LCDs (SHARP, etc.) are finally losing that “washed-out” look, so I may opt for one of these soon, and end up with the 61″ in the bedroom. I will never buy a DLP, because the color wheel throws away so much brightness potential (1/3 the time illuminating each color!). Also, after the newest round of 1080P lieing from Samsung (their so-called 1080P set was only 1280×720, hey, that’s my resolution AND needs a color wheel) I’m inclined to go to LCDs and forever forego projection.

Drupal to e107

I’m still deciding how I’m going to handle boulderheights.org. Initially, I was quite happy with drupal (recommended by Dan) but I can’t figure out how to do some more complex (and necessary) operation with this engine (in particular, how to make the forums readable only by registered users). Now I’m in a conundrum, because about 20 users have added their information to the drupal database, and the website is advertised via a sign on the corner of Deer Trail and Lee Hill. I’ve checked, and I can’t figure out how to move people’s accounts over to e107 (also recommended by Dan, has the ability to lock out forums). Anyone have a solution?

WordPress for everything

After switching Cassie over to WordPress for her “single web-page turned blog”, I overhauled my own website, which was a mixture of B2evolution, FrontPage and custom PHP scripts to WordPress. I hope you like it. From the authoring point of view, the WYSIWYG TinyMCE editor is awesome. The conversion from blog engine to blog engine took around 10 minutes. The actual conversion of the website took me quite a while, but it’s been years (like, 6) since I did anything with the website.

wp-button-5.gif

Along with this conversion, I combined my “site proper” with my blog. In the process, many old links are probably broken, but I’ll be working on fixing them over the next while.
