 On my newly-updated-from-0.18 backend/frontend combo machine equipped with
 two DVB receivers, I'm seeing SVN 8554 mythbackend both freezing and dying
 intermittently. It's probably related to fairly frequent signal errors in
 the stream caused by a weak antenna. 0.18 used to skip in recordings and
 complain in the backend log, but run stably. 8554 will die at the same
 situation. Logs repeat the following error hundreds of times when this is
 happening, which I take can happen during either commflag or transcode.

 Discarding Frames.

 Sometimes this will repeat indefinitely, sometimes the process dies.

 I've been unable to isolate a recording small enough to post to repeat
 this problem with, but I'll keep trying.
