Similarly the recordings directory doesn't look the same:
drwxrwxr-x 2 mythtv root 4096 Sep 11 08:33 recordings
as compared to:
drwxrwsr-x 2 mythtv mythtv 20480 Sep 11 07:31 recordings
How do I get an "s" in there and what is it's numerical value? 5
I tried creating the directories as mythtv user, but permission was denied,
and with sudo, I don't know mythtv's password. Should there be more to the
command "sudo chown mythtv recordings"?
