This shouldnt be an issue (that of only root user having access to
your tv tuner). I to have this problem with one of my dvb tuners (due
to the way I modprobed it). But, it works fine in mythtv.

I think this is because, although you run mythfrontend as a normal
user, mythbackend runs as root, and its that that is actually
accessing the TV tuner card(s). Mythfrontend just connects to the
mythbackend.

Feel free to correct me anyone if I'm wrong here.
