The last chapter FMV

After i rip it it looks fine. I play it in VLC player and looks good. But when i open it in virtual dub the left corner is all pixily. I dont know why. And when i import it into the project it looks pixaly. Any ideas? All the other FMVs play and look fine.

Does it look pixelly if you open it in a different media player? VLC might be doing some smoothing to hide it from you :p
