Check it out IF. The DLs have ALL of the extras, the SLs have a FEW of the extras and still have motion menus and stuff. The PURIST is the only one with no menus or anything bonus at all.
As for the PAL DL, I don't remember, since as you well know, I don't have to deal with the 4% speedup. But the PAL SL does have SOME extras and menus, just not all of them.
I tried to cover all of this on OT's FanEdits.com, but it looks like there have been some tweaks to them.
