To recreate the bug, all I had to do was go to mythweb and refresh the recorded programs page twice.

top two for top:
5726 root      18  -2  621m 133m  20m S  197  3.4  16:22.84 mythbackend
8134 root      19  -1  566m 153m  31m S   11  3.9 110:11.85 mythfrontend

process 5726 is taking 200% -- 100% on two out of the three cpus of my tripple core amd phenom

ps -ef | grep 5726:
