Movie Maker Project Delays After Publishing!

I've been working on a project in Movie Maker and after a few days of editing, I had it where I wanted it. My problem is that once I publish my movie, my editing becomes delayed by 1-2 seconds (which it doesn't do in the Movie Maker preview - it's perfect in the preview). I've tried publishing it multiple times as an MP4 and .WMV file and nothing is working - I keep getting this delay in my editing. My audio and video are syncing fine, my editing is just coming out off after I publish. Does anybody have any idea why this could be happening and what I could do to fix it? Thanks in advance!
