[mythtv] mythbackend problems with 0.15.1

[James Pifer]

I've had some problems with mythbackend since upgrading to 0.15.1. 

Initially the symptoms were: 
A recording would start and may or may not finish. At some point,
usually during the first or second recording, recording would stop (the
file size would stop growing), but mythweb would still show it as
recording. Mythweb itself would still function, but start acting very
sluggish. Killing and restarting mythbackend would bring it back up
again.

On trying to get debug traces it's acting slightly differently, actually
worse. Now it crashes during the recording and the backend seems to
totally go down. Mythweb stops working and gives the page asking if the
backend is running. I usually tell when it goes down by looking at
mythweb and seeing the file size not growing, even though it says it's
still recording.

Anyway, my debug is seems rather lacking, but it's at the bottom.
Hopefully I did it right this time. My apologies to Isaac for failing to
complete the steps the first time. 

Thanks,
James
