I recently had a computer built for my home theater. It is a 1GB AMD with a Verto GeForce 6600 GTC video card. I have had a hard time setting the resolution on my projector, but finally got HDTV, 720p to work OK. I am using it in Clone Mode and last night made some adjustments and now neither screen will come up when starting the computer. I see the Windows welcome screen on both then blank. Any advice on how to get into the system. Secondly, I'm having a hard time getting the DVD decoder set up properly. I'm trying to use the new NVIDIA decoder, but now all of a suddent, Microsoft Media Player want recognize a DVD. It says my license has expired. Any advice on getting better quality with my projector and with getting into the system would be greatly appreciated. Thanks!
