I don't think those apply for the way I have my system set up I just
want to play PAL content on a PAL TV so I avoid using a deinterlacer
and need the graphics card to maintain the interleaving on VGA so
there's almost no processing at all.

> I too have an nvidia card and am experiencing some issues. LiveTV looks HORRIBLE right now for me. I just ordered a new video card, I'm hoping this helps. I also think I need to update my nvidia drivers. I believe I am using the legacy drivers (173.14.12) when I should be using the current ones (177.82). My video card is coming in today and I'll know more about this tonight.

Strange to have a difference between recorded programs and live. I
thought the frontend treaded those in a very similar way, although
I've heard lots of reports of problems. live TV has worked fine
for me on two VIA-based ITX boards I've tried.
