Using an HD3000 to receive QAM broadcasts in myth requires some hands-on
work *after* doing a scan. The HD card + mythtv combo does not populate
the mysql database with the correct entries (at least not yet..)

Browse to:

www.cuymedia.com/doxygen-dev-docs/html and looked for the page setting out
the MythTV Database Schema for some info on the dtv_multiplex, videosource
and channel tables.

Then browse to:


You will need the dvb-apps which are linked about one-third of the way
down under the heading Using the DVB kernel modules(linuxtv.org). If your
kernel is recent (2.6.14 or later 2.6.13) you do not need to do all of the
stuff in the first sections. But read that anyway.

Then browse to gossamer threads and search for the mythtv-users list
thread "Sweet! PC HD3000 QAM_256 working, now about importing those

This sets out the process required to poke the proper values into the
proper places in the mythconverg database tables.

Note that it is absolutely necessary that you have a 'good' channel listed
as the starting channel for your HD3000 card before you attempt to run
mythbackend or mythfrontend. 

BTW, the 'channel number' used by your provider has no relationship to the
frequency on which the channel appears.
