Your best bet is to head for the local second hand shop/dodgy DVD shop, and look for a '2 Pints special/Only Fools' or 'Making Of' DVD. These will probably give you enough info to make it easier to get through.
Also it give another excuse to watch old 2 pints/only fools.
The new series sucks, with no Jonny then 2 pints isn't worth watching. But they often have a lot of 'behing the scenes' stuff, which would be useful for what you need.
