Hardy x86_32, Fusion HDTV Pro tuner card, onboard intel graphics chip
Am in Brisbane Australia.
All channels except channel 7 work fine in MythTV.
Using vlc 0.8.6h channel 7 (all including HD) work.
Myth doesn't appear to be getting a channel lock on any of the channel 7 signals.
Nothing obvious in the log, signal strength on all the other channels appears fine and like I said channel 7 works fine in vlc.
I have gone into the backend and deleted and rescanned all the channels already twice and imported the working channels.conf that use vlc uses - everything except channel 7 in myth is fine.
Nothing obvious in the logs (frontend or backend).
