Hi Dick et al:

We've had the same problem with our videos, and our Apple Engineer at  
Miami indicated to us that is it a purposeful time-sync lapse built in  
to the streaming server to prevent piracy and copying the videos from  
third party software. Apparently it is a known issue at Apple, but the  
company will not address it. Their view is that any video over 25  
minutes long is deemed a potential "copyright violation" piece of  
material. The time-lapse sync problem is not an issue with QuickTime,  
but rather with the streaming server itself. Unfortunately, I haven't  
found a way to "hack" though the software to break whatever is causing  
the time-sync lapse... and Apple won't help.
