Windows Media Center is not seeing your TV tunder card, correct?
You can use the tuner card in Windows, but not Windows Media Center, correct?
--------------
1. Have you updated the drivers for the TV card?
2. Have you tried uninstalling / removing the TV tuner card and use it in a diferent slot on the mother board?
3. What is the make and model of the TV Tuner card? Have you read that company FAQ from thier site?
Please list the specs of your PC, i.e. make and Model or the parts inside: Motherboard, Video Card, etc.
Good luck!
Peace!
