players/devices (vlc, mplayer, android, ios, etc.). As such

My thinking was that this script was meant as a user job to be run
after a TV recording is made to convert the MPEG2 recording to H.264
for the purpose of viewing these recordings on a low powered device
like an Android tablet. My concern here was that it would auto
remove commercials based on commflagging (not good, since the
commflagging is not good enough to just auto cut) or that it would
not preserve the commflagging (so there would be no commercial
skipping watching the transcoded recording). If this was not the
purpose of the script then never mind.<br>
<br>
How does one watch recordings on a tablet then? I tried the android
Mythtv frontend and Mythtv viewer apps, but could not get them to
play any recordings. I came to the conclusion that all recordings
had to be pre-transcoded first, which is what I thought this script
was all about.<br>
