Not to get too far ahead, Harmy, but for ESB have you considered reaching out to Snicker to see if he would produce a source benefitting from his channel recovery tricks? I contacted him to see if there was any way to help by volunteering to run part of the process on other computers, but he informed me that the process relies on numerous liscensed plugins.

I know the general consensus is that ESB is in better shape than the other two films, but for me the lack of dynamic range, partcularly in all of the space shots (seriously, look at the first imperial fleet shot - there's more shadow detail in the GOUT for chrissake) makes me wince every time I see it. The asteroid chase in particular is so bad that parts of the TIEs dissapear into the starfield and make them practically invisible at times. It's even more of a shame as ESB is without a doubt the best shot and lit film in the OT and it's dynamic range and pallette have been mangled since 1997.
