Darth Mallwalker said: Use that value if-and-only-if Harmy's STAR WARS card appear at frame 689, like NTSC GOUT.
(690th frame, since first frame is called 0 -- I'm going by memory here, so double-check)
The Star Wars card does appear at frame 689 as when previewing the Avisynth script in Virtualdubmod, so that should indeed be the 690th frame. That's fortunate because it means that Belbecus' mix should synchronize perfectly. The delay values that hairy_hen posted above match the newsgroup .png. Well remembered, hairy_hen! It looks like it should be plain sailing.
So far I've spliced in the footage with fixed subtitles and added new mattes. I'm rendering out my AVI now. Harmy, I'm uploading a small preliminary sample of the NTSC encoding so you can have a look.
EDIT: Harmy, your Inbox is full.
