It's not terribly confusing.  First, you need to hook up your cable, without
the set-top box, to a cable ready TV and determine what channels you get "in
the clear.  This is independent of Myth but will give you an idea of what
your service provides.

If the clear channels are all the content you want to watch:  PVR-150,
connect to coax INPUT on the PVR-150.  Sound will be captured via the tuner
in this case.

If the clear channels are only a subset of your content, the your STB is
required.  In this case, you hook it up to the s-video INPUT on your PVR-150
and use an IR blaster to change channels on the STB as needed by Myth.  This
will always get you the channels you've paid for at the expense of some
simplicity.  You will also need to capture the audio via audio inputs on
your sound card in this scenario.

In both cases, Myth will output to your TV via the s-video output of your
videocard/motherboard and audio via the sound card.

THe HVR-1800 is an HD tuner and will only tune clear QAM channels that
Comcast provides you.  This is likely to be a subset of the clear channels
you get without the set top and totally at their discretion.  While not a
bad idea as a second tuner (if you want to get a little HD content - this is
what I do with a combination of 2 AverMedia A180 HD tuners and a PVR-500),
it is unlikly to be sufficient for your total needs.

I hope that helps.
