 I am attempting to use the removecommercials script on the backend, and it
 fails part way through, without completing:
 mythtranscode --honorcutlist --showprogress --chanid $CHANID --starttime
 $STARTTIME -o $VIDEODIR/$FILENAME.tmp

 Actual command: mythtranscode --honorcutlist --showprogress --chanid 2501
 --starttime 20151021103000 -o /data/mythtv/2501_20151021063000.mpg.tmp


 The file gets created and the process works for a while, but fails:
 -rw-r--r-- 1 root   root   3335990440 Sep 13 11:04
 /data/mythtv/2501_20151021063000.mpg
 -rw-r--r-- 1 root   root     81690762 Sep 15 20:33
 /data/mythtv/2501_20151021063000.mpg.tmp

 From the script:
 ./removecommercials2 /data/mythtv 2501_20151021063000.mpg 2501
 20151021103000
