Adding to a motorised system

[Earlstreetblue]

At present I have a fairly bog standard installation, where I have a TM6900HD hooked up to a 90cm motorised dish with a single lnb attached.

I have recently bought myself a nice new Panasonic TX-P42S21B which has a freeview hd tuner and a spiderbox 9000HD.

Now I'll need to change the lnb from a single to a quad, so am I right in assuming that isn't going to be a problem, as in the extra weight of the lnb? I'm also assuming, changing the lnb won't be a difficult affair.

Plus would there be any benefit in running a cable not only to the two recievers, but also to the freeview tuner? My guess is that it would just be a waste of time.

It's easy to replace an LNB, but I don't know how two receivers could operate one motorised dish.
The Freeview TV needs a well-aligned terrestrial aerial, so the dish isn't involved in that at all.

What is the make of the dish?

Not sure, but it looks very much like a Triax (90cm).
