What about making a DVD set with only the four original documentaries? (The Making of Star Wars; SP-FX: Empire Strikes Back; Classic Creatures: The Making of Return of the Jedi; From Star Wars to Jedi: The Making of a Saga)
I don't care much about the other material (and I already have the DVD made from the Definitive Edition bonus LD). A 2 DVD set, with 2 documentaries on each DVD, would be fine! (as a DVD-R can easily hold 2 hours of video)
