I really beat on my system last night trying to duplicate this, but 
can't.  I tried 12 forward 30s skips and a couple of 6s back skips and 
even more severe combinations and couldn't get mine to fail.

What type of source are these recordings coming from (satellite, cable, 
OTA)?  Are they HD?  I only tried SD recordings (cable and satellite) 
because I still haven't upgraded my CPU to play HD without audio dropouts.
