Yeah, you usually don't want to have the idle rate low like that.   
What happens is that QuickTime reports that certain media types need  
to be idled as often as possible (QTVR, AXEL component, etc.).  Right  
now Rev idles (updates) these movies at the idleRate.  This isn't  
fast enough for QTVR though.  I would leave the idleRate alone for  
now and just wait for 2.7.1.  Playing with the value is just to show  
that there isn't any major problem with QTVR, just that it isn't  
being idled enough.
