Sorry for lack of updates.
At the moment I am trying some colour-correction (or colour-retiming - whatever you want to call it) of the blu-ray. I am trying to remove some of the blue/green tint from the picture, and also fix the red in Superman's costume, which appears to be too rich at times. This is just some experimentation at the moment - I have no idea what the project will become yet.
I will post some screenshots at some point to show you some results when it is looking nearer to how I want it (I'm still learning a few things right now).
