I've managed to get it more stable (now that I know the problems of the ATI 
driver, I can track down bugs easier and I have working versions to compare 
with...). But my X server often freezes when I change the video plugins 
(Linux is OK, but I need to reboot). I'll leave the GL mode in this state. It 
doesn't seem to have much use, NVIDIA is slower (Koos, Andras), ATI is very 
fast but unstable. So noone will use it...

"Resize to PAL": kdetv never had such an option. You may be confusing it with 
some other program.

There were other NVIDIA users that reported this, too. Sounds like an XVIDEO 
extension bug. I never saw this with my Open-Source Radeon drivers.
