It seems to me, as a novice, that errors in the recording stream seem
to have a profoundly negative effect on MythTV right now.

I have the at-least-once-a-day frontend lock on HDTV content. When I
go back and look at the stream it's because the audio stream either
dropped out or errored in some way. The picture is flawless, not
pixeled / boxed / etc, so I'm not so sure it's a signal quality thing.

Mythcommflag simply died at 90%

Devs: I'm not sure where, and what type of info to pull to help with
this. I'm keeping several files around that kill the frontend, and
mythcommflag hoping I can do some good with them.
