I've just been reading through the user manual of my new Samsung TV and found an entry under timer recording which says that I can "make a reservation to record a pregramme scheduled for broadcast". I assume that I could do this for one channel while at the same time recording another channel on my Sony HDD. The TV manual says that I would need a USB HDD with at least 5,400rpm but not a RAID type. I would welcome advice on suitable devices, please.
