Until now, my PC has been running smoothly - I could watch TV. Now I can't. I went on MCE > Live TV and it said there was a tv tuner problem (it was either in use or something had happened). I checked the antenna and all the cable connections to see if it was a wiring glitch. Then I rebooted. Went on MCE > Live tv and it said it couldn't play the video (the video being the live tv streaming). I then exited mce feeling angry. Later, I went on it again, this time when you go to live tv to watch, it shows a message saying NO TV SIGNAL - as usual when the you can't watch tv. plz help!!!!
