So hooking it up would be done using something like a Composite out
from the video, and a 3mm mini-stereo --> RCA converter cable, then
into the modulator.  Sounds doable.

Surprised I didn't think of those, my mom actually uses one on her
ancient TV :)  Thanks!

What about between the frontends and the backends, would that be
necessary to also have the gigabit Ethernet there as well?  If not,
I've seen some fairly cheap integrated boards that would probably be
able to handle a frontend configuration (and might be cheaper in

Excellent point, didn't think of that.  I'll be sure to watch for that.

Thanks, the cabling is in place, not a problem there.  I'd rather not
go with the MVP at this point, from what I've read it's not quite what
I would like it to be.  A full blown frontend is more likely what I'll
go for, just hoping to find mega discounts on bulk buys.

This is a great idea, a community room for HD viewing of select shows.
 Maybe a few of those series I mentioned earlier; certainly with the
option and abillty to have one in your own room should you want to
sport your own HD capable frontend.

Thanks for tip!  Actually, if anything, think of more like a community
of your family members and close friends, all living very close
together.  Something like a trailer park full of just people you know
and love.  If this ever becomes realized, I'd certainly make sure that
anyone receiving this would also have a concurrent subscription to
whatever programming source we offered.  It very likely wouldn't
become a legal issue at all.
