I ended up economizing a lot to save shelf space. I gave my 2004 and my Definitive Collection LD transfer discs to my brother when the GOUT came along.

From there, I combined sets as much as necessary. TPM was pretty much left alone. No combining done there. But for the rest...

-- AOTC
Disc 01- AOTC
Disc 02- AOTC extras
Disc 03- Cartoon Network Clone Wars, vol. 1

-- ROTS

Disc 02- ROTS extras
Disc 03- Cartoon Network Clone Wars, vol. 2

-- ANH
Disc 01- GOUT
Disc 02- 2004
Disc 03- Darth Editous

-- ESB

Disc 02- 2004

-- ROTJ

When I got my copy of the Holiday Special back from my friend, maybe I'll make that disc 3 for ANH and throw the Darth Editous thing away.
