[mythtv-users] How to set up an input to record only one (or a small number of) channels.

[Nick F]

I'm embarrassed to be asking this, having used Myth since 2006, but
never had to set this up before.

I have Comcast and three tuners - a HDHomerun Prime, a regular
HDHomerun and an analog tuner.

I'd like to set the analog tuner to record only HBO from my cable box
(and ideally the HDHomerun to record the basic network channels).

I'm not sure how to set this up.  All my channels are via cable - so I
have only one lineup with Schedules Direct.  So - when I link my
analog tuner to my source the analog tuner wants to be able to record
everything (which I don't want it to do - I want it to only record HBO
which the Prime can't do obviously).

What's the missing step - I've googled, searched the wiki and the list
archive to no avail.

Thanks!
Nick
