Hi, I have a movie in two mpegs. I converted both mpegs to DVD format and used Shrink to add both and create new DVD with full movie. When played from folder on pc the DVD is fine however after burning onto disc the second half of the movie has a green bar along the top and bottom of the screen and the middle part jerks up and down constantly. I'm using good media and burning at 4X, even tried 2.4X to see if that made any difference but same result. Any ideas?
