Hi Richard,

You may want to look at the scripts by 'Skinah' at:
https://forum.mythtv.org/viewtopic.php?f=2&t=1261

You can set them as user jobs. I had good experience with lossless
encoding hd-pvr recordings with the 'tv' script in the past, after
configuring it for lossless and adjusting cutpoints to keyframes
(don't know if this last step is actually necessary, just remember it
was needed with RD Vaughn's lossless cut script).

from the script:
#!/bin/sh
# Script written by 'Skinah'.
# This script will export a mythtv recording to a folder in a friendly
readable name that is
# compatible with KODI. It will honor cutlists and also use handbrake to
compress recordings
# to MP4 to save HDD space.
#
# It now supports lossless cutting of MP4 HD footage as well as MPEG2.
# All of this is done without changing Mythtv's database or recordings,
this way if a
# mistake is found in the cutting of the recording then before myth
expires the recording, we can
# rerun the job after adjusting the cutlist manually.
