Cheers for the input guys but I'm not planning to retire this release, only to take into account more modern sensibilities of what is appealing and give people a release that is more pleasing to the eyes of a casual viewer. This requires a little adjustment of fleshtones and a slight adjustment of saturation. I've checked the sandcrawler clip with my retro (perhaps better to call it 'print'?) settings and classic settings on my TV and the classic clip is undoubtedly more pleasing to the eye, even if the other clip feels more 'right' in terms of the print.
I want to get all three versions sorted out while its fresh in my mind so I can put Star Wars behind me and move onto Empire Strikes Back.
