Well I checked Episode III out in another player, and the mystery snow/grain is still there in all the same places.
I can only speculate at this point somebody attempted to apply artificial film grain, and frakked it up totally. :(
How does crap like this pass quality control?
If anyone has the ability to take screencaps so you can all see what I'm talking about, it would be very much appreciated. I don't have a Blu Ray drive for the PC yet.
I need to dig my DVD out and see if this stuff is visible, although I'm betting it isn't...
