Hello everyone... I have been experiencing this problem for awhile... When I click on my media center and then go to live tv I recieve a video error message and says to restart mce or my computer.... This started happening recently and used to work fine... What I did... I restarted my comp, reinstalled my video car drivers and my tv tuner drivers, I actually removed it from my system and then put it back in... While the tv tuner was out of the system I went to mce and clicked on live tv and still recieved the same message... makes me think it has nothing to do with my tuner at all.... Can someone please help?? I have a Hauppauge HVR Wint TV 1800, Radeon 4850 and I am running Vista Home Premium x64... Thanks everyone!!! ...
