Francesco, that did indeed work to start Media Center without giving any errors. However, I cannot view any video in Media Center, be it live tv from my E-Home Wonder TV tuner or a regular video file. I can hear sound, but no video comes through. Seeing as you have the exact same video card as me (Radeon 7000 VE), I was wondering if you are experiencing the same problem. I may just have to break down and buy a new video card, but I don't want to spend a bunch of money. This is an extra computer that is using a spare TV tuner I had. My main computer with an up to date video card is running Media Center with no problem.
