[mythtv-users] Dual tuner info

[Poobah]

Does your basic cable have anything that the cable box doesn't?  If not,
you don't need the Television Input -> Listing #2 for cards 1 and 2.  It
is redundant cabling and extra degradation with that many splitters.

If you choose 2 different types of listings, there will be double
channels in the listings, even if some of those channels are the same.
Another problem is that if you start watching live TV on the basic cable
only card (assuming the other 2 are busy), the only way to force it
later (after the others are done) to switch over to the digital and get
the extra channels is to drop out of Live TV and select Watch TV from
the menu.

I lasted in this mode for about a month before I got a second cable box
and re-configured all my Listings...

So there's no way you can tell myth that a channel in one source is the
same as a channel in another?  I'm not in this situation yet, but I
forsee I will be in the future.

My ultimate goal is to have three tuners, two for my DCT boxes and a
third with regular cable.

So, for the first two, no problem, just set the same source as they are
identical.

The third presents a problem as just adding another basic cable source
would result in duplicate channels ... unless ...  and i'm basically
working this out as I type here so bear with me ...

Listing #1: Digital Cable with all basic channels removed
Listing #2: Basic Channels

Tuner #1:
	Composite Input -> Listing #1
	Television Input -> Listing #2

Tuner #2:
	Composite Input -> Listing #1
	Television Input -> Listing #2

Tuner #3:
	Television Input -> Listing #2

This would probably make a bit of a cable nightmare at the back and may
require a few cable splitters to setup.

MythTV is smart enough to know that it can't record the television input
of tuner 1 if it's using the composite already, right?  Would this work?
