Yesterday I discovered that the new box set of the original series of Reginald Perrin has edited episodes for most of series 1, for similar reasons to the edited version of the 1973 Steptoe & Son Christmas special.
This is most annoying, and surely happens due to pure laziness on the part of those in charge with releasing the material. I'm sure most fans want to see the shows as they were originally broadcast.
Quite a few programmes also have edits for political correctness purposes, e.g. in Fawlty Towers the line "is it your legs?" has been removed, in Bottom the line "thieving bastard gyppoes" has been dubbed over, and apparently the Only Fools and Horses DVDs are a car crash of PC edits. Though apparently the US versions are uncut! Also, series 3 of Reginald Perrin has some edits for PC purposes when Reggie meets a black character.
Anyone know of any more?
