I was thinking of buying a DVD player to hook up to my TV then found that you can play DVD's on a Play Station2 (ok so I haven't kept up with technology, too busy messing about with my computer).
Being a little on the tight side I was thinking why not buy one and kill two birds with one stone, watch films on DVD and be able to play games as well.
As I don't know much about these gamey machine thingy's I have a few Questions.

Are they any good as DVD players?
Do I need to buy an extra Ram card and why?
What extra's, if any should I buy?
Has anyone got any tips they can give about these machines?

Thanks in advance
