chanid is used only internally by Myth.  channum is the number you 
specify to tell Myth to change channels during LiveTV.  Therefore, 1044 
will not work.  S26 should, but doesn't because you have duplicate 
channels (with duplicate channums).

You can change the channum to anything you want--as long as each channel 
you've defined has its own unique value (no two channels can have the 
same channel number--even if they're on different sources).  Just don't 
change the freqid.

So, fix your channels.  The NULL freqid makes me think you did something 
like scan your PVR-150 for channels.  You should really populate 
channels on analog sources with mythfilldatabase (or the "Fetch channels 
from listings provider" button in mythtv-setup).

The best way to fix it is to use the "Delete All" button to delete all 
your video sources, then recreate video sources, channels, and input 
connections (but don't scan analog sources).
