However, if you have different video sources, you may want to use a 
negative priority on the SDTV channels.  Using a positive priority on 
HDHR HDTV channels may mean that MythTV decides to record an HDTV show 
you don't like that much on the HDHR rather than record a better show 
(with a +1 priority) that isn't available on the HDHR (and, therefore, 
never got its +1 from the channel).  See (all of) 
http://www.mythtv.org/docs/mythtv-HOWTO-12.html .

Then again, why leave the SDTV version of the channels in the HDHR Prime 
video source if you don't want to use them?  Aren't they just garbage at 
that point--garbage that's getting in the way of getting what you want, 
that's slowing down scheduling and loading listings, and that you'll 
never need?  If you have the HDTV versions of the channels in the video 
source, I can't imagine any reason to keep the SDTV versions there, 
too.  (I.e. why have NBC and NBC HDTV in one video source?  I'm guessing 
the same would apply to Discovery and Discovery HD--assuming they have 
the same content all the time.)
