The setup worked with CVS from about 24 Dec. I recently updated the CVS
and recompiled (last night 5pm UK time). Now the DVB won't tune.
It also completely crashes mythbackend... surely the behaviour for the
driver should be to terminate gracefully to allow other recordings to
proceed?
Anybody any ideas?
