Has anyone else had major problems with the 650 working only for a while and then getting "tuner not found" or "capture card not available" messages? I can get the card to fail in Vista just by changing some settings in Virtualdub Capture. And then it won't come back until I reboot the machine. I used to have occasional problems with the tuner failing with Media Center, but now that I'm messing with capturing through other apps it is very apparent that something is very wrong.

I switched to XP and the card is rock solid now. It has never quit once. Used Catalyst 8.11 for both XP and Vista.
