http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocalThere is a free vista codec pack one can obtain for versions of vista that
do not come with advanced codecs such as the Vista Business Edition. This
codec pack is based on open source libraries but I would not call it
consumer grade software (simply because of its hundreds of options and the
level of documentation).
To maintain scientific grade quality, often lossless compression is required
such as the QuickTime Animation Codec. So far I have not been successful in
figuring out what products would allow lossless encoding with other
algorithms such as MPEG-4.
The issue of not being able to play certain movie files is probably due to
companies desire to create revenue opportunities with movie playback
software (e.g. Windows Vista Business does not natively play DVD movies). It
seems when implementing those revenue opportunities, backwards compatibility
is compromised.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocalI've also had a problem with AVI files on Vista.
On my HP desktop running Vista, AVI files from one of my digital cameras
and some older AVI files from work just don't play. This means that none
of the Microsoft home video editing tools work with them. I've tooled
around the Microsoft site a little and done some Google searches but
haven't figured out how to get the codecs into Vista.
On my daughters' Toshiba Vista laptop they all work just fine. So if I
really really need a file, I chase them off YouTube and IMing and use
their laptop.
Good luck with Vista.
