Bridgidmac, if it's just an ordinary TV you wont have ITV Hub. I don't have a TV that comes with it built in but I have a Now TV stick that you just plug into the USB port on the back of your TV. It gives you access to all the catch up channels including ITV Hub and BBC iPlayer. It only cost about £25 and I've found it really useful. Of course if it's a very old TV and it doesn't have USB ports you wouldn't be able to use one!
Apparently there are six episodes.
