[mythtv-users] Multi Rec and Input groups

[Mike LaPlante]

Browsing through the archives I found this.

Where a user was able to get an input group setup with his Firewire 
cable box and an S-video capture. He checked out the multi-rec branch 
back in June.

I want to do just this and its my understanding that multi-rec has been 
moved into svn trunk(http://svn.mythtv.org/trac/changeset/16003). I'm 
currently running Axel's bleeding repo version (which rocks by the way), 
so I started poking around today and can't find anywhere in mythtv-setup 
where you would do such a thing.

Am I missing something? I only see "capture cards" "video sources" 
"input connections". Not sure how I'm supposed to tell myth which two 
devices need to be grouped.

Can't seem to find a wiki page on input groups. There's a multirec one, 
but I'm not really doing DVB stuff which seems to be all that covers.

Any information one could provide would be much appreciated.

Thanks
Mike
