Check your tuning timeouts.  If your database was originally created a
long time ago, the tuning timeouts will be much smaller than the
recommended 10 seconds (10000 milliseconds) that gets set when
creating new DVB tuners today.  I think the tuning code takes a little
longer to tune now, and it may be going over your tuning timeouts.

There should be some error messages in mythbackend.log to show you
what the problem is.  If not, try adding "-v record" to your
mythbackend command line.  In Ubuntu, add this put in an
/etc/mythtv/additional.args file:

ADDITIONAL_ARGS=-v record

and then restart mythbackend:

sudo systemctl restart mythtv-backend

Or you can run this command from any command prompt:

mythbackend --setverbose record

which tells the running copy of mythbackend to set the verbose record
logging option.  Be careful to cut and paste that command, rather than
typing it.  Getting it wrong can lead to you having two copies of
mythbackend running at once.
