Interesting. Well, avifile reports the bpp as 1, so it's
especially strange that aviplay (which is based on avifile)
does color, too.
I sincerly hope that what we have here is not some strange kind
of lossless indexed color compression...
Would it be possible for you to create, say, one second of video and
send it to me in some way? I could open a ftp server somewhere
for that purpose.
I'd really love to take a closer look at this format...

You have to generate audio.swf in a way that it has the same
framerate as video.swf, e.g. like this:
wav2swf -r <framerate> audio.wav -o audio.swf
Where <framerate> is the one reported by "swfdump -r video.swf".
Now the following will bring audio and video together:
swfcombine -mT audio.swf video.swf -o combined.swf
