It is easy enough to follow as I said before.
Visually this is constructed from bits of the DVD versions of TPM, AOTC and ANH:R so if you are familiar with that material do you really need to see it in DVD quality to figure out where the edits are?
If the quality of the screenshots are so offensive to you than perhaps it's right you shouldn't download it (though I can't see why you would make such a big thing out of not downloading it, surely one post explaining why gets the message across).
Any dispute between TJ and A-M is between them.
If A-M did use TJ and ID's material without express permission that would be bad form but as I said we all do it even if we are posting screen captures from the DVDs (I've never asked George Lucas' permission to stick naughty slave girls in his shots, I didn't even ask the naughty slave girls if they minded dancing for Jabba).
I was blown away by the material that ID and TJ put out and I was really looking forward to Reborn (and I still hope one day the idea will get the treatment it deserves).
This isn't their edit, it a different edit and I hope this one, when it's finished comes out well and is distrubuted to a high standard.
Until then I don't mind looking at the rough version and giving a few tips (if any enter my gnarled brain).
