Hi; I need help very badly; I made my own Media Center using MCE2005. Every thing working fine when I use my Computer Monitor, but If I connect my TV set to the computer, I will get my Windows Startup screen and Windows, but when I press the green button on the remote, The display on the TV will be black nothing will appear, the only thing you can see on the screen is the Mouse arrow. Can anyone help? I am using the flowing hardware:- Motherboard:- MSI K8N Neo4 Platinum, AMD 64, Socket 939 TV Tuner:- Hauppauge WinTV-PVR-500MCE VGA Card:- ATI Radeon X600 Pro
