Holy crap, you guys are amazing! Been reading the thread now and trying to
let it all sink in. Lots of new info for me :)
So now with the explanation of the Rogers digital box, I'm curious. Let's
say I get another Rogers digital box (same as one already in family room).
Now if I want to use it exclusively with Myth, I would what-- plug it in to
my server? ie., Connect it to the PVR-150 and my PVR-150 now captures from
the digital box?
With the Rogers box having its built-in Guide and all that, how would that
affect my desktop PC as frontend? Would I have to have the digital box
plugged into my desktop PC as frontend? Or can I just use my mythfrontend as
I am edging closer to another PVR-150 or 500 for now but just want to be
sure and not waste $70-$80 if it makes more sense to spend a bit more and
Thanks a TON!
