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:

ah 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
