2. Freesat, now i have a old sky dish on the house but it will be nealy 10 years old but have read that i can use this for a freessat box ? Will i be able to get a HD box and run it off the dish with maybe getting a new LNB ?
The old dish should do you and you may not even need to change the LNB, just plug in the HD Freesat box any away you go.

Just one or two things:
If you want multi room viewing you will need to change the LNB to a "Twin" or "Quad" one and run a feed to the other room.
If you get a Freesat box with twin tuners (view one station, record another) then you will need to change the LNB as above.
The dish might have moved slightly over the last couple of years and it might need to be re-aligned.

As for Freeview there are a number of box's out there that have Freeview & Freesat (HD) combined in the one unit, you just take a feed from the Sat dish & the Aerial into the back of the unit and you have all on the one box.
