Hello,
I am using Magic Pro ProHDTV Extreme 4 pci-e TV card, and it is normal to watch TV in my computer.
Very strange that one day I cannot watch TV . Somebody at forum told me that he has this problem too, he fix this problem by  deleting the Avast. So , I try to uninstall AVG. Yes , this can solve the problem , I can watch TV in computer now.
Could anybody tell me what the problem is ? Should I never install AVG again ?
Forgive my poor English.

Wing
Best regards
