Im trying to create a motion menu in dvd-lab. I have an ntsc 720x480 mpg that I add as the background. I setup the objects as I want them, then export as an overlay. I take the overlay and the orig. mpg and bring them into vegas4. I rendered out a new mpg with the overlay on top. But now when i add the new mpg into dvd-lab the overlay no longer lines up with the new mpg.

anybody else seen this happen?

Thanks in advance
