Mill Creek claims that Quantum Leap is back to the original form on their blu ray release. I haven’t seen the dvd releases to know if true or not, but the licensed music is still there. I have yet to get through the entire series though.
If you can confirm that the original music has been restored, I’ll update my list.
I can confirm myself that the blu-ray releases restore the music in both the US Mill Creek release and the UK Fabulous Films release, however both releases are not 100% the same
On the US Mill Creek release, the episodes Genesis, Lee Harvey Oswald, and Trilogy Parts 2 and 3 (originally parts 2 and 3 were edited together into one movie) are presented in their syndicated two part versions, as the original NBC versions were movie versions. On the UK Fabulous Films release, Genesis and Lee Harvey Oswald are both restored to their original movie versions, however parts 2 and 3 of Trilogy still remain in their split form.
From what I know, the original movie version of Trilogy Parts 2 and 3 have never been seen outside of the original NBC broadcast, and even the original Universal DVD releases had it split into the two part version (though the same DVD release presented Genesis and Lee Harvey Oswald in their movie versions).
