That would be the optical soundtrack from the print, or optical track, containing the Dolby Stereo 2-track mix. The audio has some subtle background pops and scratches but it doesn’t overpower the sound mix. These anomalies are what audiences in the theatre watching the film would have heard at the time of the showings. The optical track audio would be in sync with the video because it came from the print. That audio track should have came with ISO file. On the spleen, that audio is the only audio on the ISO file.
Ok, Thanks. I actually found another version and tried it just to see if it was in sync. It too was about 3 frames off, but after adjusting it, All was well. Kind of odd that it stayed true throughout. I wouldve thought with the later missing clips it would jumped off sync a bit as the movie ran, but it didnt. It was a 2 ch only version. I found the GOUT versions on spleen and will give them a try as well.
