Oh, and technically, it is a bug, but it's a very low priority one 
because it almost never occurs in situations where it can't be worked 
around.

Basically, if the same episode of a show airs at the exact same start 
time on 2 different (= different call signs) on different Video Sources, 
MythTV schedules both for recording.  However, since it's very unusual 
for the same episode of a show to have the same start time on 2 actually 
different (= don't normally broadcast the same content--not just the 
same channel on different sources) channels, it will very seldom occur, 
as long as users actually mark channels with substantially identical 
content (= same channel from different sources) as being the same (by 
giving them the same call sign).

The only down side is that it means that users can't use different call 
signs on the channels to allow them to use "this channel" rules to 
specify from which channel (meaning which input) to record a given show 
unless they're willing to get the duplicate recordings of shows where 
they didn't use "this channel" rules.
