Nero Vision and DVD Video screen alignment

I’m using nero vision 4 to make a dvd with 5 avi’s that I have. Everything goes smoothly, the video and audio are synced and all that good stuff, but the video doesn’t line up correctly with my television. I’ve tried changing the aspect ratio but it doesn’t help. I’m not sure what else to do, any suggestions? Thanks

Bah, I hate to bump but this is driving me up the wall, oh and I’m using divx avis if that makes a difference.
