Team Blu is doing an HD upscale that I believe is sourced from several different laserdisc transfers. ANH is available on Myspleen now, the other two are supposedly coming soon. More info here: http://originaltrilogy.com/topic/Star-Wars-OT-and-1997-Special-Edition-Info/id/10550
Pretty sure it’s from a TV broadcast.
Really? The description on the spleen says the main sources are TB and GKAR. I’m not familiar with TB, but I was under the impression GKAR was a LD rip.
