So you did get 720p content working on the FX200 PCI with XvMC?  I'm 
fairly sure now with the existence of various PCI HDTV capture cards and 
PCI HDTV decoders (MyHD, etc) that hardware accelerated HDTV playback on 
a PCI device is certainly in the realm of existence.  I would imagein 
though, that unaccelerated playback would be difficult.
