Bought my PC months ago (on XP Pro), since then, no problems with playback at all (using PowerDVD and WMP). Then all of a sudden, last week or so, the DVD reader has started to reject DVDs! It can play audio fine, but data and movie discs are causing problems. Example: I inserted He-Man (I have the POWER!...well used to!) disc into DVD drive. Takes a while, but finally reconises the disc and asks what I want to play it with. It starts to play for about a few seconds and then just locks (picture and sound). I can't CTRL+ALT+DELETE or anything (that includes banging my head off the keyboard)! I tried this in both media players and have tried re-installing the driver, but no joy. I have not installed any new software that might confilct, so what could be the problem? Has anyone had this problem before? I know that movie files work because my DVD-RW drive picks them up and plays them fine! It's just the DVD reader that is being a pain in the membrane!
