Are there any captures of the LaptNek sequence out there? I'm even considering and experiment, using the album version of LaptiNek and re-editing the special edition Jedi Rocks video footage over it. However, I'd prefer to just find a good transfer of the movie version of LaptiNek and reinsert it as it was originally presented.
Update:
I screwed around with this for several days, dealing with a strange A/V sync that I couldn't figure out. Finally, I ran the "Fix GOP Errors" utility and it brought the video stream back in sync with the audio streams. From there I used MPEG Video Wizard to do some frame accurate editing, cutting out Hayden and replacing Shaw from the rip that was posted earlier. I output the video stream and it stayed in sync. Because I only used the actual 3 shots of Shaw & company, if there is any color drift, it isn't noticible. The in-between shots of Luke & Leia still come from the DVD and thus look nice, and the "ghost" effect on Anakin, Yoda and Obi-Wan masks any color difference, at least to my eyes.
I didn't pull out "Wesa Free" yet because I didn't want to dork around with the 5.1 audio yet. That said, I may tackle reinserting Lapti-Nek next in a custom fashion. I'm looking into the feasability of using the album version of the song (since it's the only one available) and re-editing the "Jedi Rocks" video around the audio. It may make for a unique way to see the movie. It should be fun, if nothing else. I think it'll be easier to pull and replace an entire segment like this instead of the heavy-sound-fx laden "Wesa Free" ending.
