It was some setting that I forget now but after a bit of poking around I finally fixed that.
Thank you all if you can help. I'm using a WinTV-HVR-1600 tuner card. Within Media Center 2005 (and I have Rollup 2 and .NET Framework 2.0 installed) it works excellent, except for this one little thing: MCE won't scan multiple channels from the same source. <p>By this, I mean for instance, PBS is channel 6 in my area. It scans the analog channel 6 and the digital channel 1061, however PBS has channels 1061-1064 available, and MCE won't get 1062-1064. <p>I know they are there because WinTV2000 will scan them, but WinTV2000 is horrible, it will not give me full screen video, while MCE does a good job on full screen. Have any of you run into the same problem, and did you find a way to fix it?
