You can let the console user own the devices if you configure it in
/etc/security/console.perms.d

$ rpm -qf /etc/security/console.perms.d
pam-0.99.3.0-2
Comment 2 sangu 2006-06-21 16:28:31 UTC 
$ rpm -qf /etc/security/console.perms.d/
pam-0.99.4.0-5
Comment 3 Kostas Georgiou 2006-06-28 10:39:01 UTC 
This wont work if you want to run something like mythtv which runs as a daemon.
What I do is to add MODE="0660", GROUP="video" in the dvb section of
/etc/udev/rules.d/50-udev.rules and add the users that I want to the "video" group.
