Rob,

The most likely cause of corrupt output files that comes to mind would
be if you ended up with multiple copies of the script simultaneously so
that more than 1 copy of the decoder was writing to the file at a time.
Your script creates a unique working directory for each invocation, but
the output files would be the same if whatever mechanism you are using
to invoke the script
were to overlap.
