[mythtv-users] missing channels

[tilman at wiredmail.org]

Hello, 

I recently completed a mythtv install.

So far everything seems to working correctly except for that I am only able to
watch channels 5 and 6.  All other channels come in as snow. 

I have tried setting my frequency table from us-cable to us-cable-hrc to
us-cable-bcast.

The channel data and TV guide information is coming in correctly and I am able
to change to all my channels.  

Does anyone know how I could begin to debug this problem? What might the
problem be and where should I look?

thanks
