[plug] mythtv channel scan

[Jim Householder]

Hi

I'm making some progress with mythtv.  I can watch the composite input 
ok, but no digital yet.

I adjusted the permissions on /dev/dvb so the card can be seen and 
identified ok, and the channel scan button is now active in the channel 
editor.

I'm stuck here.  I have no idea how to set up the scan parameters.  I 
suspect 'auto' is sufficient for most, but what frequency should I use?

TIA
Jim
