got the set and i also noticed glue on some of the discs. unplayable. some had glue and other's had ths type of film residue. here we go with the replacement game... **update** I received a replacement order and all discs perfect.
Okay. Got the discs and most appeared to have some markings in the discs themselves that cannot be polished off but they still play on the dvd player. For some reason, it won't play on my PC, they just stop after the Hasbro intro. I guess I better play and scan them all on my dvd player to make sure those markings are rendering them useless.
