Playstation 3 -- ISO Troubles

I've recently discovred this website about a week ago and tried to install a few PS3 games for my console [that is Jailbroken]. Some games work fine while others have issues?

1.) Iron Man 1 (PS3)- the game would load however I couldn't move my character.
2.) The Incredible Hulk (PS3)- can't even press start or do anything.
3.)TMNT: Mutants in Manhattan (PS3)- the iso couldn't load.
4.)Transformers: Devastation (PS3)- the iso couldn't load.

I was wondering if anyone can help or have ever faced the same issues loading these particular games or familiar situations?
please reach back if it maybe the roms themeselves or few tweaks I need to do with make with my console. Thank you for reading this message and have a wonderful day.
