No, actually a video source is a source of video programming content.  
Therefore, since you can only plug one source of content into a single 
input of a card, you can point only one video source per (/input/ of a) 
capture card.

The program listings source is the source of listings data describing 
the content available through a video source.  What you actually want is 
a way to associate multiple listings sources with a single video 
source--but it's completely unnecessary functionality in Myth...

Kind of, but actually xmltv provides all the tools you need.  See tv_cat 
(and the info about it/other XMLTV tools on the xmltv lists/fora/wikis/...).

That's definitely an XMLTV-related thing, and I think there has been 
some talk of doing something like that (but extending beyond 
satellite).  I think Chris Petersen has done some work toward it.
