not a digital alteration - but a massive change to the movie in “When Harry met Sally” when released for DVD:
they had to replace music and songs for licensing reasons - which changes the mood of the pivotal end scenes…
also the movie cuts to black for the end credits (instead of running the credits over the actors chatting away - they also cut out of the chatting pretty harshly and much earlier)
The only mention of this I could find anywhere:
https://www.npr.org/2012/01/03/144624329/the-big-bad-swap-the-problem-with-replaced-musicah so I did some digging and it appears you misread, all physical home video versions are intact music wise (otherwise it would’ve been reported years ago most likely), it’s the digital versions that have the changed songs
which is still a shame either way
I did some searching myself a while ago (since my copy of the movie is pretty old and terrible) and at least the 2001 and 2007 DVD releases are the new (crippled) versions 😦
Our public library has both DVD releases - so I could test-watch either. Both of them were the changed movie… 😕
Not sure though if there are earlier DVD releases (or releases in different countries) - or whether the BluRay releases are the original version…?
Would love to find a better copy of the original version (my copy is cropped to 4:3 and looks like it was copied to DVD straight from some Beta master tape 😄 )
(it’s easy to check which version is which: the original has the end credits running as a transparency over the actors talking - the new version cuts to black before the end credits start)
