Just watching my copy of the Great Escape that I bought last year, and noticed that it skipped quite badly between about 1:38:00 and 1:46:00-it would play a couple of frames, then jump ahead in this whole span. I've only watched this disc once before, and I can't remember if it did this the first time. I think it might have, and I never got around to inquiring about it. Has anyone else had this problem with this disc? If it's a defective disc, any idea how I might go about getting a replacement?
