Well, in the case of digital you can have more than one virtual
channel per transponder.

With over-the-air ATSC it is common for the major networks to have two
or sometimes three channels, but usually the other channels are a
lower-resolution multicast of the main HD channel, or something of
lesser value like a weather channel.  Hence the value isn't really
there - it's not like you're going to find the NBC and CBS HD channels
on the same transponder.

When you start talking about ClearQAM though, you can have multiple of
what I will call "good channels" on the same frequency since the cable
company tries to jam as many channels as possible into the same space
(and with the cable companies further compressing the quality it gets
easier).  So you can have cases where you want to record two shows at
once and they happen to be on the same channel, but as a user I don't
think this is exposed anywhere in MythTV (although I could be wrong
about that).
