The first thing that occurs to me here is that mythtranscode should abort if it believes it has found no audio stream. Video without audio would be rare, and non-existent for the broadcast TV that our users will be transcoding.

Transcoding the file without audio and deleting the original in the process is unacceptable, better to refuse to transcode instead.

The original recording is not deleted, it keeps it as it is. Mythtv just errors out here. If you analyse the files mythtranscode produces you see no audio on them.
