Then I'm lost as to further diagnosis. Since the hdhr is a standalone 
unit, using udp there is little additional code needed in myth to get a 
unit working. It should *just work*....Getting different channels on 
each scan sounds more like an antenna problem. Have you tried an amp on 
the antenna? I needed one to get the signal high enough to work 
properly. Try it without any splitters in the feed first.

Can't help there...
