Most likely the GOUT disc for ESB has a darker picture then the GOUT disc of SW as I used the same colour settings for Empire as I did the revised SW disc. :) Regardless I don't intend to spend another two weeks fixing this, not when if it bothers the viewer that much they can always adjust the brightness of their TV to compensate. ;)

When I watched Empire to check it for problems I did pick up that it was slightly darker then SW but it wasn't a massive difference and I just figured Empire was suppose to have a slightly darker picture to match the darker tone of the film's story compared to Star Wars and Jedi.
