Bad picture on PS2

Hi

I have the same TV as this but it is a different model (LE26R73BD). The picture quality on normal TV (just useing the built in freeview) is ok but real life images are slighty blurred but cartoons or CG movies are alot clearer I live in a poor signal area and I think the ariel may need looking at so I need to use a signal booster some people have told me this may be the reason for that I have also found some sites that tell you how to calibrate it to get the best picture quality but i have yet to try this. The main problem I have is when I use the it for playing games on the Playstation 2 the picture is really bad things are very blurred and straight lines are jagged I am just useing the normal cable from PS2 to TV and the 3 jack plugs are going into a scart converter so they can plug in one of the scart ports do you know of why this is or anyway I can improve the picture. I hope I explained that ok and hope you can help.
Cheers
