Little stutters when playing Skyward Sword

[Shadolin]

So I made absolutely sure I had the latest version 4.0-1442. same audio and video stutters and that weird spot where it seems the internal resolution is set at 1x (look on the right side, her hair, neck, the sailcloth and corner of her mouth as well). It does that at any time whenever a model appears in that zone. I'll post a video is I absolutely have to but I'm not sure how useful it will be with Youtube's compression and all. It might be hard to see.
