Having a big problem with powerdvd XP4, every time i insert a disc it causes a reboot. it gets to the splash screen and sometimes the FBI stuff then reboots. Up until a few days ago it was fine. HD playback is good and flawless. I have recently updated TT to 1.5 and regionkiller to version 2. Have patched powerdvd to 1811. The dvd rom is region free, I think the problem could be regionkiller because dvdgenie works ok and the discs start. ASUS p4b266 with 1.6p4, 256 ddr, R7500 with 6166 divers, RME sound card ( latest drivers ). Win XP pro, Powerstip doing 720p for HT300. Any sugestiond before i do a format and reinstall?
