Since the analogue and the digital tracks are printed in the same pass through the printer they would all have the same synce error then. Listen with headphones and see if there is a difference with the left getting centre digital and the right getting analogue centre

Gordon, that's just not true. It all depends on the original offset of all tracks relative to the pic. They are independently set up...not all necessarily correct.

They are all set up to the same pip on the leader. The way to test it would be to confirm the system sunc with headphones and listen to the track in question
Also if there was a diffence screen the leader and listen to the pip at the 2 sec point and see if they match
Also the optical analouge track neg contains the DTS timecode so it will match the sync of the picture also the SRD and SDDS is sometimes on the same negative depending on the printer style
