[mythtv] CVS hangs at end of recording when watching while recording

Fri May 2 10:11:28 EDT 2003

I'm running CVS from yesterday.  If I go to the guide and hit 'R' to 
start recording a show, and then go back to watching it, when recording 
stops, the current image freezes.  The backend repeatedly outputs:

Backend stuffed up in RequestRingBufferBlock

I've attached a backtrace.
