Huge apologies for the delay in replying to this (never buy a house by water!!). Many thanks for the replies, it was kind of you to take the trouble.
I have managed to get everything set up, only to find that my viewing card isn't accepted by the Vu+ box (my fault for not checking first!) The only other thing that seems a bit unusual to me is how fussy this box is, it will quite happily accept one usb stick, and won't play at all with another.
Thanks again for your help.
