Ok, I have been watching Star Wars very close looking for anything that shouldn't be there. Well I found something. I don't know what it is called, I wish I knew how to post a screenshot.
When the Falcon is fleeing the Death Star Han says they are coming up on ships. The next shot of the Falcon as it is flying at the bottom of the the screen these little grey like boxes start to appear. As the frames go on it gets worse.
I don't know if you knew about it or not. I don't even know what it is. Or even if it can be fix. I wonder if it is on the dvds. I am about to check.
