The Tower Room Flashback definately has dialogue that is not in any of my previous versions, bootleg VHS, Pro VHS, VHS dub from Laser Disk, and SP DVDr copy from TCM.
We hear a laugh and Charles saying "more of your dreary moralizing, brother?"
Then we hear Gabriel yell "open the door" and Charles responds with "trying my patience brother." The annoying thing about this added dialogue is the fact that it's not synced with the lip movements.
The scene ends with Angelique repeating her lines about bringing the painting to life as a voice over and we see the portrait. Very strange.
It's one of about two dozen audio mistakes on the transfer. The original audio source they used is of the 97min R version, and they had to make edits to it, in order to make it match the 94min picture. The tower scenes is one where they made a few bad decisions about what was supposed to be in there and what wasn't. The laugh and "moralizing" lines occur in shots from the R version where you can see the cast members saying them. They should have been edited out. The repeat of Angelique's "bring the painting to life, etc." at the end of the scene, does not belong in the 94min version- that should only be in a fully restored director's cut. The same for the music that now plays during the dining room scene- Curtis and co, dropped it from this scene when they mixed the short version. It should not be in the DVD transfer.
Previous video transfers were done "open matte" showing more on the top an bottom that was meant to be seen, theatrically. On the older transfers, for a few shots, where boom mics or floor mics would have been visible because of the extra head and foot room visible, the framed them tighter, but just for those shots.
TV broadcasts in the late 70s and early 80s would actually have been of a film print, shown entirely open matte with every boom and floor mic, gloriously, and incorrectly on display...
I hope this makes some sense.
