I have the Episode III PAL original DVD, and there's something annoying about it: there's a vertical line in the left side of the image during the entire film.
Sometimes it's harder to see, but it's there.
In Mustafar it's more clear and the line is purple.

I've resized the image to see it more clear.
I've checked this in my brother's disc and the line is there too.
Is this normal??
