After a few hours of regular usage [can't pin down any specific reason that this would happen] all of my music and videos will give me a "Sorry, this type of media cannot be played" error. The files play normally, but they dont work sometimes and I have to reboot to get them working again. Has anyone had this problem before help me out? Or maybe someone who knows what might be wrong? I'm thinking of just going to trade in my Droid at the store, since I just got it on Sunday.
