well im running windows XP with SP2. I have the Nvidia pure video decoder for running DVDs on my tv....Yes I checked that and it is set to single display. As for the video drivers the most updated drivers are installed.....last update was 11/06. And there is no error messgae really, just the window popping up asking me if i want to send an error report. If you want i can view details and copy/paste them.
