I had the same problem. If your tv is relatively new then an RGB scart cable will fix it. But your TV must support RGB. Most new TV's do. I purchased the BLAZE Scart cable from Play.com for £12. Work's a treat with crystal clear picture. If for some reason your TV does not support RGB then your only other options is to buy a new TV or I purchase a modulator, which although goes through the aerial still gives a good picture and converts it to colour. This will only cost £5 and I have one that I didn't need in the end. But I suggest that if your TV has Scart and especially if it is a 21 inch TV, it should support RGB, therefore get the RGB Scart. The picture is definitely better. - Hope this helps.
