Very good save there Andy. By spreading out the effects in the areas
that required heavier computer processing you eliminated (or reduced)
the bottlenecks that were causing the jerky playback.

No, Wait-for-Frame If Frame is Loaded) only allows you to test and wait
for a section of the movie to load. In local playback all of the movie
is already available and loaded so all Wait-for-frames are immediate.
The Wait-for-Frame compensates for the Web (or IntraNet) delay.
Likewise preloading objects in an earlier frame hidden from sight would
not affect the quality of the display either.
