QT Movies playing roughly

[Graham Samuel]

I've got an app with a couple of really trivial QT movies, each 
consisting of about 30 frames  plus a soundtrack, set to loop until 
stopped. One of them shows a motor with a little propeller going 
round. The thing is scripted so that the propeller can go at 
different speeds and either forward or backward. This works fine just 
using Apple's QuickTime Player on my Macs (version 5 or 6), but when 
it's in a player object in a Revolution standalone, the motion is 
extremely rough. The soundtrack seems to work OK, but the visuals 
either miss out frames or stop completely. On restarting the player, 
one gets a bit of movement and then the thing goes all choppy again. 
The other movie behaves the same way but the lack of movement isn't 
so obvious because of the particular animation involved.

I need to use player objects rather than Revo animations so that I 
can let the user move them around the screen and so that I can script 
the forward/ reverse/ speed change behaviour.

Is this a known problem? Is there anything I can do about it?

TIA

Graham
