Rendering issue

I’m having a strange issue. I rendered an image at a high resolution and I’m getting strange bands throughout the image. It’s not quite color banding, it’s like parts of the image shifted during render. This is for a big project I’m working on, I really feel like the bands are going to hinder me badly. Anyone have any ideas?

Here’s the image. I dunno how well it’s visible on here. If you can’t see it, let me know, I’ll email it. t=1331276331

Nevermind, sorry, blender render wasn’t working, but outside blender, it looks ok.
