(ducks head...) a 46cm TV with a composite-in video socket... from a GeForce 6200.
So I guess that probably doesn't really qualify as 'gorgeous', but it has to be said that the image out of MythTV is quite a bit better than the GNOME desktop behind it. Even at 800x600 on a PAL signal. And definitely better than our otherwise average analogue reception.
Oh and the composite encoder on the 6200 is really very good*. I happen to have an expensive VGA->PAL converter that I plugged in once out of curiosity and I was surprised to see the picture was actually no better.
Wade.
