exporting HD-video in final cut pro x

I have filmed a wedding with my HD-video camera, and edited it with final cut pro 6. Now I'm ready to make a DVD but when I exported it using quicktime movie with current settings, and I have it checked Make Movie Self-contained, it came out horrible looking. It's very pixelated every time I move the camera. Backgrounds are moving.

Can anybody figure out what I've done wrong?
