Lately I've been having trouble with my XP Media Center's DVD drive - the common problem of still thinking it has a DVD from earlier inside it even after I've ejected it and put in a second movie. I have to shut down and restart the computer each time I put in a different DVD if I want the new DVD to be recognized. But even more oddly, most recently I discovered something else: After ejecting a DVD, if I go back into the Media Center and Play, the old DVD comes up as if it was still inside the computer even though it isn't! The menus, the whole movie, is still there, even though the disc is back on my shelf. I'm not sure what is causing this, or how to stop it. Any advice? Could this be something that Nero added to my computer? I don't have Nero running but maybe it is running something in the background?
