Well, unless someone proves me wrong...I believe Mike was right. According to Macromedia technote 4061, these are the only methods that can be called using javascript.

Play()
StopPlay()
IsPlaying()
GotoFrame (int frameNum)
TotalFrames()
Rewind()
SetZoomRect (int left, int top, int right, int bottom)
Zoom(int percent)
Pan (int x, int y, int mode)
PercentLoaded()


What a bummer.
