On a Windows Vista-based computer, you try to configure a combo TV tuner in Windows Media Center. This combo tuner supports both ATSC and NTSC signals. However, you experience the following problems:
The combo tuner is not detected by Windows Media Center.
Windows Media Center does not correctly configure the tuner when you use a manual tuner configuration.
When you configure Windows Media Center to receive both over-the-air digital TV (DTV) and analog cable TV, you can view only the analog channels. This problem occurs even though the digital channels appear in the guide. When you try to watch one of the digital channels, you may receive the following error message:
Cannot Play Program The channel may not be supported. If you cannot tune to any other channel, restart Windows Media Center or restart the computer, then try again.
