I'm probably not explaining it properly.  I used the procedure in the  
Wiki for using QAM_256 to test for frequencies that were tunable.   
One of the frequencies that I tuned into was obviously FOX.  I change  
the [0003] entry in my channels.conf to FOX.  I import into Myth as  
explained in the Wiki.  I populate the data which creates the proper  
entries into dtv_multiplex and channel table based on the zap2it  
lineup. I then do this:

  Fixup

In order to fix my channels now, I noted the mplexid and serviceid  
from each channel that had been imported and then removed them from  
the database. I then inserted those entries into the channel rows  
that mythfilldatabse created.

I ran mythfilldatabase again just to be sure and found that  
everything was in order.

So I should now have the proper tuning QAM_256 tuning information for  
FOX.  What I really want to know at this point since I do not have an  
HDTV is there an alternative method based on file size or another  
program that can verify the bitrate and/or capture size?
