[mythtv-users] How to transcode+cut commercials 100% lossless

[Bobby Gill]

Okay, also I just noticed while watching a recording I ran the script on
that it is skipping during the episode, I hit E and loaded the cutlist, it
keeps seeing commercials during the episode apparently and skipping a few
minutes, but of course it's just the half hour show at 21 minutes with all
commercials cut out already. What's going on? In Edit mode I hit C to clear
the cutlist but as soon as I come back to the recording after escaping out
to the menu, it still does the same thing ???
