Not used the Myth channel scan, but I took the slightly different route of
manually pinning down all the channels with dtvscan /dev/dtv, then building
a profile on zap2it, then manually tweaking the channel values until
everything tuned properly in myth.
I'm on the CVS from about 5 weeks ago, but still using the HDTV drivers
rather than the DVB ones, which I couldn't get to work.
