As it is setup, the job runs after the recording is done.

You need to put the script in a file called makempeg2 that is someplace
in the path of whatever user the mythbackend as running as, the file needs
to have "chmod +x makempeg2" done on it so it is executable, and then
you need to add in the user job with the full path to where you
put makempeg2.

The conversion could take 2x+ the time of the recording if you machine
is slow to convert it down, it depends on how fast your machine is, and what
kind of HD it is (1080i, 720p, ...), You will also need to have mplayer/mencoder
installed on the machine for the script to work.
