I have a Dell PC and, despite uninstalling and reinstalling dvd player programs, I keep getting the message above when I want to watch live TV and to restart but the video decoder isn't in use. I can watch DVD's though in Media Center. Has anyone had this problem before. I've tried ringing the card manufacturer (hauppauge) but they say it's a Software problem. I've already paid Dell for their software help and they are hopeless. Nothing they've suggested works. I'd be really grateful if anyone knows the answer or any suggestions.
