[QUOTE="devilkoala, post: 345913, member: 70371"] I am also using a ComPro hybrid tuner and I get similiar problem. I also tried WinDVR and re-install but neither could help. I find there is a serious of repeated errorm message in the log, which seems to be thrown during Analog Channel scanning: 2008-12-20 12:37:48.187500 [11]: Exception :System.AccessViolationException: Attempted to read or write protected memory.
