Batch Render Issue

Amnson

So heres a video that explains my problem. When i Batch render about 60 frames in it looks like it stops and another copy keeps going. But When i do a single frame render it looks fine. Also in the video u can see i put a playblast in the corner so u can see a little more of whats going on. Any thoughts? http://www.youtube.com/watch?v=e2XEPMborYU&feature=youtu.be

Ok so if anyone has this problem i figured out what the issue is, it seems its a corrupt frame, where the batch once it hits just messes everything up, So find the frame where the artifact first appears, and set your batch to START on that frame, seemed to fix the issue.
