Create a channel lineup and enable/disable channels based on channels listed in the Channel
Editor in mythtv-setup. Make sure the channel name and number in Schedules Direct matches
the display channel name and number in the Channel Editor in MythTV.

Note that MythTV uses the ATSC channel numbering as specified in the transport stream, not
the remapped cable channel numbering so you will need to select OTA/Antenna as the source
in Schedules Direct. However a mapping must be made to ensure that the listings correspond
to the correct channels.

Fixing HDHomeRun Channel Scanning in MythTV .20

Note these instructions are seemingly obsolete, and have nothing to do with channel scanning not getting a channel because the signal was not strong enough. (mythfrontend, but surprisingly not mythtv-setup, has a configuration setting for minimum signal level to offer the channel. Default is 65%)

In order to get channel scan working correctly in MythTV .20, you need to get the RPM's that Jarod Wilson patched with the .20-fixes including the fix for HDHR. Update the following packages:

http://dl.atrpms.net/mythdora/4.0/i386/os/MythDora/libmyth-0.20.1-156.3.md4.i386.rpm
http://dl.atrpms.net/mythdora/4.0/i386/os/MythDora/mythtv-setup-0.20.1-156.3.md4.i386.rpm
http://dl.atrpms.net/mythdora/4.0/i386/os/MythDora/mythtv-backend-0.20.1-156.3.md4.i386.rpm 

or the Easy Way:

cat << EOF >> /etc/yum.repos.d/mythdora.repo
[mythdora]
name=MythDora 4 - i386
baseurl=http://dl.atrpms.net/mythdora/4.0/i386/os/
enabled=0
gpgcheck=0
EOF

yum --enablerepo=mythdora upgrade \*myth\* 

You should be able to scan channels using mythtv-setup now. If you have any problems (missing tables and such) try deleting all the channels first and then rescanning. I ended up getting a clean start by deleting all channels and capture cards then starting fresh with these packages.
