i feel you brother , its really irritatating<sp
here is ur fix
the BLUS / USA version seems to work better.
delete the BLUS????? (folder for smackdown ) from game.
start the game from bd mirror (in multiman its select + x( maybe you wanna use it just to get the game working)
let it copy to the harddrive and you should have no problems.
ps: it seems to work better on internal but i got it running fine on external.
(ik there is a fix to install somewhere ill have a look and post it)
