Looks like we missed each other by a few days Eric!! um dont know if this is of any help but I know that the system is dfferent than most developments. I found out that sky isnt installed in the standard way as the ariel system is part shared in some blocks but not in others.
Is it spanish tv you are after or sky? If its sky then take the digi box back as it wont work even if its a euro one where one would assume you get free view.
Another great contact I made is Warren- a TV and sky expert. Really friendly and professional (plus he used to be a magician and did loads of card tricks when he came round!! Wicked!!) He knows the set up at La Entrada well. If you dont manage to sort out the signal them give him a call and tell him I gave you his number-
