Ok, so I returned the movie and got another one.
This disc worked on the first try with no stuttering.
I noticed that my first disc had a creaking sound when you applied pressure or bent it slightly, like it was two peices rubbing against eachother. THis one does not, like it's a single solid disc.
I also noticed on my first one that when I tried the hot soapy wash thing that water got inside the very inner ring of the disc, like there was separationg there between the layers. By the way, soapy water did not help the disc, in fact it wouldn't even play at all after the wash.
However, I am happy again with my exchanged disc.
Seems like a Dual format disc manufacturing problem to me.
