Please mail me your channels table from the MythTV database. I use
tv_grab_dvb to get my radio listings and would be happy to try and get
you up and running. The fact that you can watch the channels in LiveTV
makes me believe most of the underlying DVB setup is correct, but
there are a couple of issues stopping the recordings and listings
import working.
