I have two embedded .swf's, one is a presentation and the other is closed
captioning text for the presentation. The presentation contains controls with
play/pause, rr, ff, and a button to turn the closed captioning text on and off.
I use LocalConnection() to sync the two presentations together with the
controls.

The problem I am having is that once the presentations are synced and playing
independently, after about 10 seconds or so they become noticeably out of sync.
If I use any of the controls to re-sync the two swf's, they again become out of
sync after approximately 10 seconds. Both have a frame rate of 30fps. Any ideas
as to why this is happening would be much appreciated. Thanks.
