My old favorite, iOpener, stopped working as of iTunes 6. With all the hubbub about the cracks, someone actually put a decent user interface it, called MyFairTunes6 . It’s really slow, and doesn’t work as well as iOpener, but it does work to convert .m4p’s to .m4a’s.
Still needs work:
- Better than real time conversion like iOpener would be nice.
- Conversion to same compression ratio (lossiness) would be nice.
- Telling iTunes where to find the new cut would be nice.
