For me it was:

Original (snapper case / flipper)
Director's Cut
Superbit
Ultimate Edition
Blu-ray

What's this about a different "director's cut" of The Fifth Element? Are you sure you're not thinking of Leon?

HD DVD's 61 discs
36 new
23 double dips
2 triple dips - Smokey and the Bandit and Caddyshack

Blu-Ray 62 discs
32 new
29 double dips
1 triple dip - The Rock

I did have a couple Blu's that were double dips that I ended up trading away for other discs because I felt the SD was superior. I had the 4 disc SE of Pearl Harbor with the R rated cut and all the extras and The SE of Black Hawk Down I chose to stay with the deluxe SD of that as well.

I only counted original DVD's or LD's in the double dips. Anything that was VHS or a DVD-r wasn't counted

Of my meager collection of 25 Blu-ray disc's, 15 are double dips.
