As a sideways thought - not that I want to put you off swfmill! - you might want to take a look at ffmpeg, which can take a sequence of stills as input and produce a flash video (or nearly any other kind of video) as output. Don't know if it can handle your odd timings, but I think it's worth a look. If only to save your users the pain of loading 1000 jpegs!
