Let's say we continued on the same path for ESB.

0 = first frame
711 = STAR WARS title card appear

and the following reel change
30988 = r2
59815 = r3
91134 = r4
122461 = r5
151133 = r6

^ that's my numbers when I've inserted a empty frame where I know one frame is missing (last frame in the shot of the asteroid hitting the Stardestroyer).

Provided the reel changes were not changed for the SE and that no additional frames are gone from TB and G'Kar.

I've compared a few sources on this, all missing an occasional frame in different places, but time-lined them so that missing frames are taken into account.

I got exactly the same reel change numbers before comparing to the 2004 DVD with the revised Emperor communication scene removed (it fits perfectly).

So it looks like we're onto a winner with this one. Do you have the reel change numbers for ROTJ?
