A couple of this to keep in mind here:

1.) I'm pretty sure jpeg2swf puts 1 image per frame of the swf it creates.
This would mean when embedding it, no matter what you do, it will
match that of the host swf. Which is why 1fps and 50fps both played
the same when it was embedded.

2.) 50fps is pretty high for an animation of near fullscreen jpgs.
Even 30fps would be hard to maintain for this type of animation.

The fps of an swf is not like traditional video fps. It is not a guarantee
it will play at that speed. It is more like a saying "don't exceed this
fps".
It could easily drop to 10fps on slower systems during playback.
There are ways around this by adding audio to force a sync and skip frames.

3.) I'm not completely sure what you're trying to do. Are you trying
to create 1 animation, embed it, then play it back at different speeds?
Something like that would involve writing custom code to manually
advance frames in the animation at different speed intervals.
