ok, I did a partial restore, gave me the opportunity to scan for new
open channels on my QAM tuners (found 2!) as well, and to clean it up
in general.

still doesn't seem to work though, from the backend I see this,

If I replace --profile autodetect with default or mpeg-2 the same
happens. if I replace it with -m it works fine, mostly. it processes
most of the file, sometimes the transcode completes, but I've noticed
that a few random recordings will still fail at some point along the
way,
