Actually, in this case I've only selected one file... The file to be
demuxed exists in /video/recordings (myth's recordings directory), and
for some reason, it's looking for it in the destination directory
/incoming/mythburn... Looking at the file names in the log I'm pretty
sure it's only trying to process one file.

There are a number of problems in attempting to complete these last
steps. First, the audio and video streams to remux have already been
removed (it appears they are present before the mplex -o command is
executed, but the script deletes them when the error occurs... I
watched the directory contents during this process). Second, the mplex
command isnt added to my /bin directory or path, so I can't run it
from the /incoming/mythburn directory. I expect I could do so from the
directory where mythburn is installed, however this does not overcome
the first problem.

I hope so too... Have to admit I'm rather stumped.
