I'am almost certain, that no matter how much cpu power you have, there will
always be audio/video glitches with software decoding under certain
circumstances - high i/o-load, other processes running etc.
(a friend of mine has such a ultra-mega-high-end-system running XP but didn't
hear and bought just a budget card - he must run the system completly
unloaded to be able to watch TV, otherwise all sorts of glitches apear)
Remember - linux still hasn't realtime scheduling for multimedia purposes
included, KURT was once the right way to go, IMHO, but it didn't made it.
##A dedicated hardware decoder is therefore really useful for undisturbed
Besides you can use a much less power hungry system and still have some cycles
to make your box more than a media-center - mine is used as a workstation at
the same time, doing email, internet, programming etc.
