[mythtv-users] what cpu is required for hdtv playback

[Erik Pettersen]

I've got a slightly dumb question:

Is the performance gain from using AMD64 on a 64bit OS more
signifigant than if you ran it on a regular 32 bit flavor of linux but
used more stable nvidia drivers to take advantage of XvMC (at least
till the 64bit driver situation is ironed out)?
