Ok, in an attempt to help not only Ady with this but everyone else, and to give everyone a common frame of reference (in more ways than one) I whipped up this shot by shot comparison of the SE and GOUT Wampa sequences. The frame grabs aren't perfectly time-synced, but rather just to illustrate which shot we're talking about. I've also numbered them, with SE specific shots given sub-letter designations.

SE is on the left, GOUT is on the right.

GOUT3 and GOUT15 were flat-out replaced.

I'm guessing that SE7a is either an insert into the middle of GOUT7, splitting it into two shots (SE7 and SE7b) or that SE7b is a repeat of the end of GOUT7. My machine can't handle running two videos in parallel to compare them exactly. I'm sure Ady or someone else can give a definitive answer.

As for MJPollard's suggestion, maybe SE23a can be salvaged by matting in a section of the arm from SE15 to solve the shoulder/elbow issue?
