Any release that omits original soundtrack music because someone was too cheap to pony up a few extra dollars for the rights...
The worst case of this was with Quantum Leap
. The second season episode 'M.I.A.' originally had the song 'Georgia (On My Mind)' for the final scene where Al talks to Beth while she dances alone. The song is even mentioned by Al to Sam earlier in the episode as bein' her favorite. On the DVD release, it was replaced with a gawd awful lyric-less tune that doesn't even sound like a real song in the history of ever.
In the series finale, Sam leaps into Beth's livin' room at the same moment, and 'Georgia (On My Mind)' is playin' while she dances by herself. And for the fifth season DVD release, the song is intact.
