There are several ways, depending on your setup. The easiest but maybe
not the best is to setup a cronjob for root and run it every hour or as
frequently as you like.

0 * * * * chown -R mythtv.mythtv /var/lib/mythtv

The other ways depend on how you get the content into the storage
directories. If it's from other PC's, then I would setup a samba share
for the mythtv directory. Add the following to /etc/samba/smb.conf

[mythtv]
        force user = mythtv
        force group = mythtv
        writeable = yes
        create mode = 644
        path = /var/lib/mythtv

and set a samba password for the user mythtv with

smbpasswd -a mythtv

If you download the content on your backend, have a dedicated user and
change his primary group to mythtv. Then the user mythtv should be able
to delete files as long as they group writeable.

And finally you could setup ACL for that directory. It should be
something like

setfacl -m -r m:mythtv:rw /var/lib/mythtv

Maybe someone here could confirm whether the syntax is correct or you
google it.
