Watched Star Trek VI - Undiscovered Country SE R2 last night (£14 from CD-WOW). The playback freezes near the end of the film at about 1:40:00 although you can ffwd past it. I've only seen this type of thing before on badly marked rental disks, but this disk appears to be immaculate. Do you think this is a faulty disk, or could it be a disc-player compatibility problem (I've got a Tosh SD220) ? Do you sometimes get disks which just don't work right even when undamaged ?
