I have three Sky receivers in Spain-

One Sky+ with Sports and movies
One Sky+ with FTA and Setanta
One Sky Digital FTA

I want to watch TV from all three receivers in each room in the house. I am reasonably technical but just want some advice on the best option with the least amount of hassle. I guess I want something like 3 video senders that can also act as three receivers. That way I can tune each telly into a different receiving frequency.

One issue why I want SCART is two televisions are Spanish so the sound is on a different frequency so SCART sorts it out (RF cable is a problem - can be done - at present I put a VCR in the system - RF in SCART out )

Can I use a magic eye in the setup?

I have no access to terrestrial television.

I am pretty sure I will have to change the broadcast channel on each satellite receiver to avoid conflicts with one another but thats as far as I have got.

At present all three receivers are in a different room and obviously have their own feed from the dish.

The problem I can foresee is that as far as I know video senders take whatever input it may be, convert it to be transmitted and it's then received on the second unit, usually the transmitter and receiver give you 4 different channels so you can avoid any interference from phones, wi-fi etc. In order to have each receiver be able to pick up each box you'll either have 3 transmitters with each box plugged into each transmitter (9 connections!) with each transmitter on a particular channel for the corresponding receiver. This method would use a video sender with switching capability but even with them on different channels I think the signal to switch inputs would end up changing every unit rather than each one individually.

Alternatively you could have 3 "regular" video senders with one sky box into each transmitter, with each transmitter on a different channel. When you want to change which box you're watching you just change the channel the particular receiver is tuned to.

Either way, 3 video senders will no doubt interfere with each other horrendously (1 can be tricky enough) In addition, you'll also have the issue of changing channels on the sky boxes. There are methods of doing this but I think they involve sending signals via rf cable - which as you've said is out as a solution. Without more expensive kit than your off the shelf video senders it might not be feasible or might require some kind of broadcast license.

There might be another solution I'm missing, but I think that you're going to be stuck with only a partial solution at best.
