Some retro TV series coming to DVD are having to have their score completely changed, due to copyright issues.
The shows affected are the likes of Canadian drama Northern Exposure and the 1960's version of The Fugitive.
In The Fugitive's case, entire underscores - essentially background music - have had to be changed because CBS Paramount, the studio how owns the property, do not own the rights to the music.

According to Variety, a change in law means that new media, such as DVDs, must adhere to music-licensing laws. This was something that was unheard of 10 years ago.
Variety points out that this might also be the reason that music-heavy shows like The Wonder Years, with its'60 rock soundtrack, aren't available on DVD - not in their original music form at least - as the price to get all that music licensed would outweigh profit.
Gord Lacey, editor of TVShowsonDVD.com, spoke to Variety about the findings and said: "If you're trying to sneak these releases out hoping nobody's going to notice you replaced all the music, it's not going to work.
"A lot of these studio releases are pushing more people into buying pirated material."
