[quote name='Vigilante']Blegh, thanks; if I was looking to get the Theatrical Editions of those episodes (either Blu-ray or DVD), what would be my best option?[/QUOTE]
They have only been released on DVD as "bonus features" in non-anamorphic widescreen taken DIRECTLY from the "definitive" laserdisc masters from 1993... they look like crap and are an insult to anyone who wants to see the Original Trilogy on modern home video.
There's a 6-disc trilogy set and they were also released separately in two-disc versions... but they're a bit expensive to buy because they're OOP. (buying the individual movies new from Amazon, for instance: $89.99, $59.95 and $58.09 with the trilogy at $215 new and $94.99 used)
