That board has onboard video, right? Have you tried playing the video without the add on card? I don't have a second video card so I can't try the switching capability..

Which slot is the card in, relative to the CPU, and have you changed any bios settings?

Does you sound setup seem to be normal and have you tried just using Stereo instead of high definition sound?

Is the High Quality DVD a Retail version or something you made?

Are you running the 32 or 64 bit version of Windows and how much memory do you have?

Did you try the video prior to installing Gom Player?
