Are you able to receive EIT programme listings, or record successfully?

It _could_ be a playback problem, rather than a tuning problem, so
during testing choose the CPU- or Slim playback profile in
mythfrontend's TV Playback settings..

The mythbackend user has to have access to the /dev/dvb* devices. Many
users run the mythbackend daemon as root, and mythfrontend as their
regular user.

If you open 2 consoles and run mythbackend in one, and mythfrontend in
the other (or redirect logging from both to two log files), you will
be able see the log ouput from both during a LiveTV session.

mythbackend is repsonsible for the tuning and recording, so its
logfile will be the most useful if it is not a playback issue.
