Well this turned out to be fun and games. First my 'user' was not part 
of the group 'video' so mythtv-setup could not open the dvb card I just 
added. I fixed that so I could use the card.

However, the video sources and input connections would not mesh up.  I 
had 2 sets of channels in the guide. One without any schedule data and 
those channels I could tune to.  The channels with data could not be 
tuned to.

For some reason when I did the tuner scan as part of the input 
connection setup it number the channels 5_1, 11_1, etc. But the XMLTV 
EPG had all the channels listed as 5.1, 11.1, etc.  This may be because 
I had built the existing XMLTV for use with mythhdhrrecorder and I 
followed those instructions.

I seem to have it fixed by deleting everything and starting over with 
video source, etc. I created the XMLTV using tv_grab_zz_sdjson_sqlite 
exactly from the wiki (https://www.mythtv.org/wiki/XMLTV) and got it 

Now I have to go though the schedule rules and see what got affected. I 
can already see the previously recorded programs have messed up data for 
the channel they were recorded on.
