I also am watching this in VLC on a Mac, so it's difficult to freeze-frame it accurately, but eventually I was able to find the exact frame numbers to be removed: 150,206 and 150,207.

Assuming there hasn't been some sort of error, that should correct the synch issue. Unfortunately, as Laserschwert pointed out, PAL-sourced audio tracks may now lose synch at this spot, and would be delayed from the video by a corresponding amount. The delay likely won't be as much of a problem as being ahead of the picture, since sound travels slower than light and we're already used to experiencing that in real life, but nonetheless solving one problem does create another in this case. However, since PAL audio would have to be slowed down to synch with 23.976 fps video anyway, this provides an opportunity to correct for the synch error as an additional step at the same time as the conversion process.

In any event, being able to use the same audio tracks for multiple video projects simplifies the matter greatly, rather than having to make additional versions.

It occurs to me that I don't have a GOUT-synched copy of the 1980 stereo mix, so now that the synch issue has been decided, I guess I'll just go ahead and make one myself. Thank goodness for schorman13's laserdisc audio archive!
