Notice that my laptop, which plays all movies fine (except hdtv of
course) is a P2 celeron 366 mhz. Much slower than any P3. Granted it
does have mmx, but with that much speed difference otherwise (not to
mention the crappy celeron cache) things should more than balance out.

IMO the problem on your system is what someone else mentioned: the
buggy "QuickTime" video layer on osx converts yv12 to yuy2 behind the
scenes, using very slow code, and also gamma corrects it in software
which is incredibly slow and unnecessary.

Must be due to bugs on the mac vo/ao drivers..

Are you sure vidix isn't supported? It would be by far the best
choice.. Maybe someone (I know there are plenty mac fans out there!)
could port it....
