Well, first off, the only “six track” mix on there is the 5.1 - the rest are all stereo and mono.
Second, there’s no 1.6 for either DNR or no DNR. There’s a 1.4 no-DNR that has a new color grade courtesy of Sanjuro, and both it and the DNR Blu-Ray ISO have a new scan of the opening crawl.
Third, MySpleen invites are closed and have been for a long time. There’s been rumblings that they’ll open up invites again but nothing official.
Ok I’m sorry looks like I just wasted your time. I thought that it was a six track mix cause that was what it’s labeled as and I don’t have any equipment to test surround. 2nd I heard that there was a new version of 4K77 with DNR I must have been mistaken. And finally thanks for solidifying my theory as why no one else was getting invites. One final question is there another platform which one can access Star Wars fan projects besides Myspleen?
