games aren't booting HELP!!!

[spank0rama]

i am having trouble with burning some games for ps2, i just started with this copy of aggresive inline... it goes to the aggesive inline screen and then freezes... now is a copy of slug fest, it goes from the games shark screen, starts to boot, and the somehow goes all the way to a grey screen with the memory card on it and finaly goes to the black and red screen saying insert a ps2 game......

i have tried burning at a slower speed and nothing...

any help please!?
