No writing to the DB happens, this script only reads values. (I'd
never even contemplate writing to the DB given my programming
limitations!!).  I haven't coded any schema version checking yet (want
to make sure the core functionality works in other territories first).

Yes.  This script is a standalone and entries only show up when
recordings are finished.  The script pulls a copy of the original
recording to the local box to work on so shouldn't conflict with

Wasn't aware of that, my experience in the past with mencoder and x264
was that it only used 1 thread unless told otherwise.

I'd be happy if someone thinks what I've produced has any value and
incorporates it into nuvexport, if I had the skillset I'd do it
