How come some DVDs I watch have unstable picture at predetermined spots. One recent example is ahem.. Miss Congeniality. Anyway, so many spots where it caused the scaler/projector to loose sync. And those spots are repeatable.
|If they are repeatable in the same spot I would suspect a DVD pressing defect or a deep scratch after the fact. Keep in mind how much data per sq inch is on a DVD. There can easily be a scratch or dent that is not visible to the human eye but more than enough to disrupt a few frames.|
