Can you show us a few shots of stuff you've painted out/on? Like the green R5?
This was a simple change of hue:

What have you replaced the shot of the rearing ronto with?
Nothing, it's just completely gone. I was quite lucky with the music there, and it splices together without sounding too weird at all.
Have you painted out the probe droids?
Nah, I kept those in, except for the one that gets knocked down as the speeder enters Mos Eisley. I didn't find it to be too bad a change.
How have you compensated for the missing frames when removing Jabba?
Do you mean the frames that were in the mix in and out of the Jabba scene? For in the inwipe, I slowed down the footage of the guy approaching the camera, which serendipitously makes him look rather sinister. The outwipe is circular, so some of the frames could be reconstructed using cut and paste from later frames. Where that wasn't possible, I had to manual move elements from later frames, particular R2 and the piggy guy who's coming around the corner in the background.
The position of the mix doesn't quite match the OT, but the total number of frames in the two shots does.
I wouldn't mind him in as long as the Greedo scene was altered to use its original lines.
