 I built 8862 and it looked promising as it seemed to switch programs fine
 and play, but after nearly one minute of the next program I get the same
 symptoms (may be worth noting that both programs were 'The Simpsons').
 Unfortunately, I didn't have the verbose logging on nor was I running the
 frontend in gdb, but it appears to be the same problem.  I'm heading out
 for the night, but if another backtrace of this is needed then I can
 create one in the morning.  I also checked the recordings directory and
 there is no second file for the 5pm Simpsons, only one for the 4:30-5:00
 episode I started watching.  Please see bold lines and inline comments
 from the log entries below.
