I have the whole trilogy EE in HD, I just always assumed, that someone just put in the EE scenes from an upscaled DVD (which is definitely true for FOTR as you can clearly see the drop in quality, but it did always seem to me, that TTT EE scenes were natively HD, I just couldn't get my head around where would anyone get those scenes in HD. So TTT was broadcasted in EE? That's good, because IMO that it is a far superior version (unlike for the other two, where the EE scenes are just a nice addition).

And these HDTV captures are actually superior in quality to the recently released Blu-Rays, as they are the same transfers but the Blus suffer from heavy DNR and edge enhancement and other nasty digital "enhacement" artifacts, which were not present in the broadcasts. I'm dreading we might get something like that for STAR WARS on Blu-Ray.
