This is a result of the Rev transition to the newer QuickTime APIs  
that report how often an application needs to idle QuickTime movies.   
How often you idle a QTVR determines how smooth the playback is.  It  
should be fixed in the 2.7.1 release but for the time being you can  
reduce the idleRate property to something like 10 and see really  
smooth playback.
