Cool. But I tried 800x600 yesterday. Wasn't much better.

I just want the quality that my regular TV has, or close to it.

That's great information. I'll try it.
By the way, I don't know if that could be the reason for the problem,
but I get "Can't get the color key and we need it" error all the time.
Does that mean anything?
Thanks!!!
