I run TV out from an NVidia card to a regular TV and the desktop certainly 
looks like crap, but the mythtv output should look OK. Is regular mythtv TV 
viewable ?

What about playing DVDs ? If it looks like regular TV you are probably doing 
ok.

I know you ATI owners hate this, but the nvidia-settings utility allows 
about a 20-30% improvement in the appearance of TV out by tweaking a few 
sliders. However, it would still suck to have a TV as a desktop.

As a sidenote, I thought that a ATI 9200 card with TV-out that my gf has on 
a windows box actually looks better than the output from my NVidia card, but 
the pain and failure to get it working with Linux was too much :-((((

Cheers
