The engine change log for 2.7.1 says that qtIdleRate was added as a  
new feature in that release:

the qtIdleRate

You can set the global 'qtIdleRate' property to specify how  
frequently to idle QT movies. Use this in conjunction with the global  
'idleRate' to control updates of QT movies.

Revolution uses the following heuristics to determine how frequently  
to idle QT players:

If the version of QT < 6 then it idles at the qtidlerate at all times.
If the version of QT >=6 then:
   a) If no players are playing and none of the visible players have  
interactive movies assigned they are idled at the idleRate
   b) If no players are playing, but one of more of the visible  
players are interactive then they are idled at the qtIdleRate
   c) If players are playing then they are idled at the qtIdleRate

Interactive movies are ones such as QTVR and Flash that do not need  
to be 'playing' in order to require updates.
