Yes, thank you for correcting terminology.  :)

MythTV Video Source - a unique list of channels available through an 
input(s) in MythTV
Schedules Direct lineup - a list of channels from a specific provider 
(cable/satellite company, OTA, ...) that are available (in part or in 
full) to one or more MythTV video sources

Though mythfilldatabase will /never/ automatically add new channels to a 
video source that's connected only to a digital capture device.  The 
HD-PVR is an analog capture device, so mythfilldatabase will add new 
channels to a video source connected to the HD-PVR.  The HDHR, however, 
is digital--and requires a channel scan to add new channels.

Therefore, since your HD-PVR can likely get /all/ channels for which 
you've paid, and only the HDHR needs a subset of the channels in your SD 
lineup, you likely don't need --remove-new-channels.

If, however, you choose to remove some channels from the HD-PVR video 
source (so you don't "waste" the HD-PVR recording something from a 
channel available on another video source), then you would need 
--remove-new-channels so that mythfilldatabase doesn't just add the 
channels back to the (analog) HD-PVR video source.
