Thanks for all the help.  Just for the record, I went down the path
described in https://www.mythtv.org/wiki/Multiple_Source_Metadata_Copy
The EIT data is better than the xmltv data and also usually reflects last
minute schedule changes.  So I created a regular cron job to do database
copies from one Video Source to the other based on scripts I created using
the above wiki article as a guide.

It's ancient history now, but when I first started using Myth, I had
different types of tuners, framegrabbers, dvb etc. all connected to the same
video source, even though they needed to be tuned in different ways.  I
guess you can see from the "channel" table how different methods have been
added over time, such that many of the fields are specific to a tuning
method and are only used if relevant to a particular tuner type.
