I loaned a bunch of DVDs to a friend who failed to tell me that her DVD player skips. Now I have them back and my DVDs skip! I've tried to clean my player and all the DVDs, but they still all skip--just the ones that I loaned her. Anyone else have this problem? Were you able to get them to play properly again? I'm SO mad! Most of these DVDs are new! I haven't even watched a few myself
