Ron,


What matters is not so much the frame rate as the rate of content delivery. 

If you do a Test Movie and use the bandwidth profiler, you can determine 

how much content is streaming and whether the rate of stream exceeds the 

bandwidth at a given connection. 28.8 is the default for this display, but 

you can change it.  With any given animation, the faster you play it, the 

more demands you make of the Internet bandwidth, but only while the movie 

is being accessed the first time (after that, it's likely to remain in the 

user's browser cache). But you could have a very low frame rate in which 

you load a large bitmap every frame, in which case there wouldn't be time 

for everything to load and keep up with the streaming sound, or a very high 

frame rate in which very little graphic content needs to be loaded, in 

which case you'd have no problem. By setting sound to stream you ensure 

that the animation keeps up with the sound, frame-by-frame, but Flash may 

have to drop the animation from some frames in order to achieve this. If 

sound is not set to Stream, and content delivery cannot keep up with the 

movie's demand, the movie will hold up while content is loading.
