Answering the question Mike didn't quite answer:

A Video Source is defined as a collection of channels that can be tuned by one 
set of tuners, connected to one source of transmissions: e.g. cable, satellite, 
over-the-air (OTA).

Therefore, if you have tuners which can receive different collections of 
channels, such as HD/non-HD, then you'll need a separate video source for each 
collection. E.g. if you have two antenna pointed different directions and 
connected to different tuners, you'll need separate video sources.

If you want to record from those sources, then you'll need schedule information 
otherwise myth won't know when the programs are being transmitted. This 
generally means Schedules Direct (SD) in the US. Mike is saying that because of 
the way SD works, all that info can be pulled down at one go and applied to your 
several sources, since SD works on a geographical basis. It also means that your 
SD lineup may be able to contain all your channels, even though some of your 
sources won't be able to receive them.
