I can't say I understand much of the threads you pointed me to.  From what
I can see the built in transcode options don't work at all and you have to
build a UserJob to do any transcoding.  I was just hoping that I could find
a built-in option that would take an existing recording with a cutlist and
just copy it, removing what the cutlist had tagged and put the file back in
place of the original.

I have a User Job that takes a recording with commercials tagged and
manually edited to create the cutlist and then transcode it to .m4v and
move it to a directory on my NAS.  My job is based on the one in this Forum
topic (
https://forum.mythtv.org/viewtopic.php?f=2&t=1261&p=7857&hilit=sendTVtoNAS#p7857
)

This script uses mythutil, mythtranscode, and handbrake to accomplish this.
I guess I could create another script to just do the transcode honoring the
cutlist, but I figured that would be one of the default scripts.
