[mythtv-users] Why does Myth HD channel scan miss some frequencies that HDhomerun gets?

[Rick]

As an experiment, I upgraded to the trunk and tried the channel scan 
again.  It still missed this particular subchannel.  I then tried 
tweaking the channel table and placed the values in that I thought it 
should be.  Unfortunately, myth still couldn't tune it in.  Just to make 
sure I wasn't missing something, I went to my windows box and the 
hdhomerun_gui was able to tune it just fine.

I guess at this point I should open up a defect since it seems the trunk 
won't be able to solve this problem.  Unless, of course, someone can 
give me a few more things to try.
