Hi terrasolo, thanks for your interest in this project. :)

Like you, I felt that many some of the changes were actually improvements and definately worth keeping. The Jabba scene in Star Wars was definately not one of them IMHO. It is far more effective to leave him as this sinister shadow hanging over Han Solo in the first two films until he's finally revealed in all his grotesque splendour in ROTJ. His added scene in Star Wars just makes him seem like a clown that couldn't hurt a fly, especially the bit when Han Solo steps on his tail, causing him to cry out in pain. I'm sorry, but the ROTJ jabba we all know and love would have had him killed then and there for that total lack of respect to his person. Instead GL plays the scene for laughs and in so doing totally undermines the threat that Jabba represents to Han throughout the rest of the trilogy. Very bad move IMHO and if I could only choose one scene to remove from the trilogy, it would most likely be this one.

As for making a 1080p mkv file, I don't see the need. You can just open the .m2ts video file that's part of the blu-ray folder and you can watch the films just fine without writing them onto blu-rays, exactly the same as watching a .mkv file.
