Also does anyone know if you can play a 720P x264 .mkv (ot .ts) smoothly if that means you can likely play HD Freeview smoothly? (not seen anyone suggest this as a test but it sounds like it may work to me, better than bying the card only to find you need a new PC)
Also if anyone can point to any hacks so that AGP cards can be made to try and decode x264 what would be very nice.
note: I understand the SD channels can not be played with CoreAVC, so I suppose when watching those the only option is PowerDVD Ultra, I assume HD channels are harder on the CPU/GPU right? If so that might work Ok, but does anyone know how much slower PowerDVD Ultra is than CoreAVC?
