I just got the latest X-Files box set (season 7) and have gone through two sets because of a glitch on disc 2, the episode titled "The Goldberg Variations." While the glitch is in different spots on the different discs, it is a repeatable problem involving pixilation and screen-freezing. Both freezes involve that episode. The DVD has the "coffee stain" some have mentioned on some single-layer disc, but this is the first time I've seen it on a dual-layer one. Anyone else have problems with this? I bought it -- and replaced it -- at the Fox Studio Store in Century City and don't want to have to go back a THIRD time.
