burning ps2 games

I've recently known how to burn ps2 game. I usualy rent the games and then copy. I use dvd decrypter to burn
But if i get a game on isohunt.com, like some people told me i extract the file with winrar wich gives me an iso files and then i just burn with dvd decrypter. But when comes time to try the game i just burned, it doesnt work.
Is there a way to be able to burn games from isohunt.com in order so they can work on my ps2 or else convert the iso file to a mds?
plz writ me back at
