Does the PS3 play all PS2 games? jumpy and laggy picture

[Malty]

I have just brought a PS3 phat to play my PS2 collection of games and to my surprise, on some of the games the picture is really jumpy and some of the games crash. is this normal? I was under the assumption the Playstation 3 older versions play all the PS2 games or am I wrong?
