I did notice that several scenes last for 2-4 frames longer than the French laserdisc video (the audio needed quite a few minor cuts to remain in sync).
BTW, the sample you posted has the fields in the wrong order - I don't know if this is your DVD recorder or something you did to the file afterwards. But it's an easy problem to fix if JD wants to re-encode to put it on a single DVD.
Now, here's a snippet of information for you. I used to have recordings off ITV for all three films - sadly, Empire and Jedi have been either lost or taped over. Anyway, in Jedi, rather than re-subtitle Jabba to fit the 4:3 frame, they pan and scanned the frame slowly from left to right, so that the 2.35:1 picture containing the original subtitles gradually "scrolled" sideways! It was a truly awful, lazy decision, which is why I remember it so well.
