Only because you've enabled the setting:
Avoid conflicts between live TV and scheduled shows
If enabled, live TV will choose a tuner card that is less likely to have
scheduled recordings rather than the best card available.
which tells LiveTV to start from the "bottom of the list"--i.e. use the
highest numbered cardinput rather than the lowest-numbered. (Or because
you haven't enabled that setting and input 7 is on the same host as the
frontend but input 6 is on a different host.)

Right, as it should.

Right, because cardinput 6 is the "better" of the 2 encoders, so for
recordings (which are considered infinitely more important than LiveTV
by Myth), the best is used and LiveTV will be "pre-empted," even if
another tuner is available. Then, the user who was watching LiveTV can
either watch the recording in progress or exit and re-enter LiveTV.

Good. No one should ever mess with the input priority unless they read
/and/ understand all of
http://www.mythtv.org/docs/mythtv-HOWTO-12.html#ss12.6 (really, all of
section 12, but /at least/ 12.6). (Of course, once you read that,
you'll realize that the /best/ approach is to never use input
priorities, but instead to use the video sources part of
clear all Input Connections, then re-create Video Sources, Input
Connections (in order of preference), and Channels.)

Nope. That's just Myth. The best solution: don't use LiveTV--Myth is
a DVR, where "R" means Recorder.
Second-best solution: get another PVR-150 that can be dedicated to the
satellite set-top box (i.e. so you have a /separate/ encoder for each
set-top box) instead of using Input Groups and having 2 STB's share the
If you want it to choose the PVR-150 that's /not/ connected to the
satellite STB, if possible, first, you'll need to do the video sources
then re-create Video Sources, then connect the inputs on the PVR-150
that's connected /only/ to the cable box, then connect the inputs on the
PVR-150 that's connected to both the cable and satellite boxes, then
