Video source does not equal listings source.  Multiple video sources can 
share the same listings source (Schedules Direct lineup)--even if there 
are channels that are only available on one or the other video source.

What makes the HD-PVR an analog input is the fact that you connect 
analog Component cables to it and it encodes the signal into H.264 for 
you.  The HDHR is digital because it simply grabs the unencrypted MPEG-2 
off the cable line (performing absolutely no encoding).

Your hardware setup is fine (and not all that unusual)--you just need to 
configure the software properly.  What you've done will work, but 
there's no reason to have multiple Schedules Direct lineups.  Just 
associate the same lineup to both MythTV video sources and then delete 
the channels the HDHR can not get from the HDHR's video source and make 
sure you run mythfilldatabase with --remove-new-channels.  If you do 
that, MythTV will download the listings from Schedules Direct for /both/ 
video sources all at once.
