First have you done a recent re-scan and if so is the channel that you
are tuning definitely on-air?

It would be useful to see mythbackend.log from mythbackend -v record.
If mythbackend is run as a daemon then to change the log level enter:
mythbackend --setverbose record

Next try enabling kernel frontend debug messages:
sudo sh -c "echo 1 >/sys/module/dvb_core/parameters/frontend_debug"

Then start mythbackend/frontend and try to tune to a known good channel.
Note the current time and then enter:
cat /var/log/kern.log

Cut out the section of the log recorded while you were tuning.  If you
post that here then maybe I can spot something.

When you're done enter;
sudo sh -c "echo 0 >/sys/module/dvb_core/parameters/frontend_debug"
