More info on m4a & m4p files Thanks to the MPEG4IP folks... Go fetch the MacOS X MPEG4 tools here. Using them you can delve into the secrets of the files iTunes makes.
Having done this, I've figured out that m4a and m4p files are really mp4 files. In fact, if you rename an m4a as an mp4, Windows QuickTime will play it perfectly, and as a bonus will extract a WAV file if you like.
Using mp4info, you can peer inside an MPEG4 file. On an m4a file, you see the excpected: a single AAC encoded audio track. On an m4p, however, you see an "unknown" encoding audio track.
These are command line tools, so you will need to play with the terminal to use 'em, but they seem darned useful.
In the meantime, if your goal is just to be able to share your m4a files (encoded from CDs or what not) with Windows machines, just rename them mp4 and play them from Windows Quicktime 6.1 (or, of course, extract the AIFF from them on the mac).
