My dear old Dad has decided to go digital, mostly because his old set has failed. He also wanted to get Channel 5 and needed a new aerial. (Awkward position of house and old, inadequate aerial.) He was surprised when the aerial-installer recommended he go for a new TV and a separate set-top ('Freeview') box as opposed to an integrated digital TV: the man said it offered more flexibility. Dad hadn't a clue what he meant; nor I. Dad had rather favoured the IDTV because he doesn't like extra boxes and cables; could anyone suggest what the aerial-guy might've meant: in words a technophobe will understand, please? Thank you.
