On some -- not all -- of my Disney DVDs, there is a lot of jitteriness on the menus. Every few seconds there is a little downward jitter -- the image snaps dow a little bit and back up again. This is not to be confused with the restarting of the menu. And it is most noticeable on "Mickey Mouse in Living Color" and some of the other Disney Treasures series, and Finding Nemo. When actual content is running off the DVD, it's fine. But it is annoying, especially when running the Nemo menu backgraouns as "Virtual Aquariums." Anyone else have this problem? I'm running a Toshiba progressive scan component out into my HD Sony WEGA. And this doesn't happen on ANY of my other DVDs.
