essentially there are quite a few different o-ot projects out there and it's really about finding one that suits the way you think!
each one is created by a fan and so if he/her idea of how it should look and you really need to create a list of things you hold dear to yourself and then choose the project that fits closest to it. i am in the process of doing this now.
i am leaning towards a trilogy set that will include as the commentary audio, i want the welding footage but i don't want the 3/4 second gap that appeared on earlier projects. the set i choose will be in dvd5 format which seems sadly to leave out zions work which will be amazing when it's done, but it will be in dl format. the list of things i want is getting shorter all the time. for instance i really like MeBeJedis work on the few frames with luke's lightsabre being rectified, i think it looks awesome but it's not a neccessity if that set won't include other things i consider more important. the new wave of projects look promising and the cowclops version is something that i think will be quite definitive. others prefer editdroids and dr. gonzo - personally my mind isn't made up yet, i am still reading up on these.
apart from a trilogy that i will agree with i am leaning towards the classic edition of ANH (just 1 disc) that seems excellent, i am hoping this has the doctored crawl though i'm not sure yet (more reading to be done) - there seems to be a boot of ANH that has the doctored crawl and the isolated score as a seperate audio track which sounds great to me but i don't think it's the classic edition which is a shame. i am considering getting hold of these two and MeBeJedis version of ANH (with luke doctored ightsabre) and piecing them together to make an edited version i consider complete. it would be nice to have a triglogy that was as faithful to LD versions as possible and a version of ANH that has been doctored/edited to suit my vision. i just need to find a trilogy set that i consider to be spot on...
hope this has helped you - bascially, you need to do a lot of reading! i would suggest sticking it out until cowclops finishes his new version (an apparent improvement on his first set known as tr47).
