Sure, I can fix those issues. Although I have based the intro on the video you posted here: http://originaltrilogy.com/forum/topic.cfm/Preserving-French-Original-Trilogy/post/577965/#TopicPost577965
I've slowed it down to 23.976fps, so the speed of the crawl should be correct (the original crawl in that video is a bit warped, so the top and bottom parts of it move at slightly different speeds). Also I've timed the SW-logo to be in sync with Harmy's video (and the rest of the video - like the Star Destroyer chasing the Blockade Runner - is in sync as well that way, so it's gotta be correct). Regarding the Lucasfilm and "A long time ago" cards, yeah, those are timed like my German cards, so I can change them to the French timing.
Do you have a reference for size and placement of the Lucasfilm logo and "A long time ago"?
