And the 20% CPU is probably due to the rebuffering which is due to the 
stuttering which is due to the data transfer issues.  I.e. the jump from 
12% to 20% CPU is not causing the issue, but a symptom of it.  That's 
also why it doesn't stabilize after reducing the speed back to real-time 
(because it's still stuttering...).
