more Avatar ripping help

[ECCOorca]

I have tried to rip from the Avatar Wii (rom) game with no luck so I wanted to try with the PC version (has FAR better models anyways) but i'm not having any luck.I have tried Ninja Ripper and 3D Ripper DX and I got nothing,I think it might have to do with it being a disc?
I have been able to rip from the ninvida demo but the models where in torn pieces!
