I tried 3 different drivers: ATI, Omega, and DNA - all current.

There is no display on my TV
-Your TV will not display anything until Windows starts; this may take several minutes.
• Set your TV to YPbPr input.
• Ensure that the HDTV Component Video Adapter is properly connected, then restart your computer.
• Ensure that the drivers in the ATI HTDV Component Video Adapter Kit have been installed.

I don't know what YPbPr input is - I'm hooking this up to a vcr then to tv. I will try hooking it up again - then rebooting - maybe that will work. Thanks.
