[mythtv-users] Ubuntu Mythbackend issue

Sun May 13 16:02:50 UTC 2018

All of your storage directories (/usr/local/media/*) must be writable by
the user which the backend is running as.
Running mythtv-setup usually tests this when the storage groups are set up.

All of my storage directories are owner=mythtv, group=mythtv and for mythtv
to work you need to run  something like "sudo chown -R mythtv.mythtv
/usr/local/media/*"

a) You must satisfy yourself that doing this meets your own security needs
and
(b) Realise that changing these permissions may "break" access to your
media from other applications or devices
