jumpy video on backup (black border)

[pjfan281]

hey everyone...got a question. i am wondering why when i burn some dvds, when i play them back the top border along the black bar/picture edge jumps non-stop...at first i used to think it was the way the dvd+rs were handing the large img sizes...but i tested a movie (which jumped) by re-encoding it down to like 4.15gb and it still jumped...so i wonder why it does this. it did it in like 3 dvd players, but doesnt do it in xbox...would seem its a player issue, but damn all of them? doesnt seem right. and all my backups are on dvd+r..and 99% of those play fine, so then i start to think its a movie issue. do certain types of movies cause this? if not what would?

Are these backups? You may want to check the original or watch it ripped on your hard drive.
