0.8.3 is the last release, but not current. As I said, use current
sources from bzr trunk.

I'll take a look, Thanks. You probably realize though that to get what I want (which is to allow for acceleration in gnsh) I have to make changes in many places - so I can't afford to keep up with the community but have to take a snapshot and work on that, making an update only once in a fairly long while. Isn't the last release good enough for what I'm trying to do?

Looking at some Flash specs might save you some time too. There is
plenty of information, as well as pointers to further reading on

I'll do that, thanks.
It would, for instance, explain why we use
frame-based control: embedded video and graphics need to be
synchronized. Most objects in Flash need to be able to work predictably
together. Frames are the most powerful element of timeline control.

Be that as it may, forcing all videos to go though this sync is a performance killer. Whenever possible video playback should not be controlled this way. A lot of high quality video embedded in flash out there is only controlled on a clip basis. Regardless my suggested scheme handles this case equally well and would lend itself for acceleration. I wish I had the time to try it out.
