as above but place a cable in for freesat receiver into port LNB 1 out to feed another other room.
But In option 1 ,do I have to do the fly lead from out 1 to input 2 because if I do this I can't do both ,just trying to aviod another cable run.
What are the restrictions on only wiring up the one input from the dish and not looping out giving me the feed out for another receiver,is it the reception or the recordability.

Using one cable you need the loop cable because the firmware assumes you have installed it so that it will let you set impossible recording conflicts that will fail when the box tries to carry out the recordings. To understand the limitations you need some basic facts
THe lnb converts the very very high frequncy signal from space to a lower frequency that can be sent down a coax cable (Its an abbreviation for Low Noise Block Downconverter). To allow more frequencies to be squashed in alternate frequencies are opposite polarised horizontal and vertical and because the lnb can't handle all the frequencies at once the frequency band is split into high and low band (at 11700Mhz). To do this the tuner has to tell the lnb two pieces of information, ie which band and which polarisation which it does by sending 12V or 18V DC and outputting a 22Khz tone to switch to HIgh frequency band. Only 1 tuner can control the lnb the downstream tuner has to use whatever channels are in the block currently used by the controlling tuner (tuner 1). Keeping up so far each frequency (known as a transponder) has multiple Digital radio and or TV channels multiplexed onto the carrier frequency. It's the job of the tuner to extract the one you wan't (demultiplex).
One last piece of information a single tuner can demux two channels at the same time if they are on the same transponder.

Look at col 4 it shows the freesat channels in each of the four blocks.
Look at cols 1-3 it shows what channels are on each transponder in the block
Still with me, now concentrate
With one cable you can record any two channels in the same block (You won't have all the ITV regions though)
If the two recordings are from the same transponder then you can watch (and pause live as a bonus) any other channel in the block (Remember two channels on 1 transponder only need 1 tuner_
If the two recordings are on different transponders then you can watch any other channel in the same transponder as either recording.
Now you know why it's not in the manual.
If you have Excel and a PC it's all available as an automated version
