to stay away from any m4a files
Just thought I'd mention that
M4A is just a special name for an audio-only MP4, which is a completely open standard, MPEG-4, Part 14 (ISO/IEC 14496-14:2003). You do not need Quicktime in order to handle M4A files, it is just one option that does handle them (because the MPEG-4 standard was based upon the Quicktime MOV container format). There are plenty of other ways to handle them though, and many of them are preferred anyway.
There is nothing inherently "evil" about the M4A file type. In fact, it is one example of a way in which Apple embraces open standards.
It will break MC's support for iPods.
Here's just one example:

I've been getting fairly regular crashes of MC12 and MC13 on my laptop, which does have iTunes 8 installed on it. It seems to happen more frequently when I have my iPhone plugged in, though it is NOT limited to these occasions. It also seems to happen more frequently when MC is background thumbnailing video files (which do include MP4 and MOV file types). I do not have anything unchecked in my DirectShow playback types (other than WAV) though, and those files are decoded by Haali and FFDSHOW, not Quicktime.
Is this likely related? I have not seen similar crashes on my other machines (none of which have iTunes installed). I'd certainly prefer not to have iTunes installed anywhere, but that isn't currently an option for obvious reasons.
I can certainly save and mail-in log files, if it would help.
