Hi, I just received the League of Gentlemen Boxset and the 2 discs that I have watched (series 2 and the extras disc) both have the sound volume going up and down throughout the discs. Does anyone know if this is a known problem with this set? I'm happy to send them back to play.com for a replacement but if all sets are all bad then I'll get a refund. I would imagine this is a mastering issue rather than just bad discs. I've done a search and couldn't find a mention of this anywhere else. Thanks.
