Sorry if this should be in htpc.

I've got a quad core intel box with 4gb of ram running w7mc.

tuner is a hvr-2200

I have a 256mb nvidia 8400gs.

TV is Sony 1080p

Every now and then we would get tv playback whether it be recorded tv or live tv really jerky. I can exit tv and playback a 9gb mkv with no prob. I've dropped the res down to 720p and now it doesn't miss a beat for tv.

I guess what I'm asking is my 8400gs under spec'd for freeview hd?
