I don't know for certain, but I do know that myth doesn't care about
the size of the file or anything about the file other than the name
of the file. If you want to replace the mpg with the mpg.tmp file
that should be fine.

I'm looking at doing something a bit different.. I am going to keep
multiple copies of the same show in different video qailities.
Some I'll keep longer than others.

... depends on your definition of 'can'. You / I can update the mysql
table with something like:
insert into jobqueue (chanid, starttime, type, status) values
(1014,'2006-10-27 19:00:00',256,1)

... you need to know the internal channel number and the start time of
the show. I'm going to work on this sql statement so I can run it
based on the filename of a file.

This will place a new job in the jobqueue. the 256 type corresponds to
my 'user job 1'. If you want a different job, let myth update the jobqueue
table with something and see what values it uses.
