Instructions (from HDHomeRun Forum)

If you are running an older version of MythTV you will need to upgrade to 0.20 (or later).

If you are using the MythTV 0.20 Ubuntu/Debian package then you will need to update /usr/lib/libmythtv-0.20.so.0.20.0 once mythtv has been installed. http://www.silicondust.com/hdhomerun/libmythtv-0.20.so.tgz

Fixing HDHomeRun Channel Scanning in MythTV .20

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.
