I've just been to that site, and it answers a lot of questions.
I get the impression it's nothing to do with my graphics card and i need to buy a new three way scart etc.
Which is crazy, because i bought one the other day, got home realised i had an old one for my portable dvd player, so i took it back to the shop. Really don't want to spend £30 on a new one. Oh well, i'l get it and if that works i'll get back to you. Going to bed now.
