I remember hearing mention of defective audio tracks on certain Prisoner DVDs from A&E. I've searched the archive but can't find any info on this. Can anyone fill me in on which discs/episodes were effected? After watching The Chimes Of Big Ben last night, I'm guessing that's one of them. It sounded awful, almost "flanged". Are the corrected versions marked somehow? Can I still exchange them with A&E? Thanks for any info!
