[mythtv-users] user job using ffmpeg

[Jim Judd]

Sorry I didn't mention that before, I have that in a script already.  I 
just included it so show what parameters I was already passing to 
ffmpeg.  There are actually two calls since I'm doing 2 pass encoding, 
but the second call is 90% the same as far as parameters go.

Calling the script from the command line works great, just not sure 
what's different when called from user jobs.
The user job is defined like "/home/mythtv/mpg2toh264.py %CHANID% 
%STARTTIME%"
