iMac G4 again, Captain America: TWS extras?

Forgot to say that I've finally put the iMac G4 up in my bedroom - Decided to bite the bullet and run a network cable upstairs, since vendors of Wifi bridges were VERY cagy about them working in client mode on an iMac this old. A bit of a PITA, but I suppose I may want to stream video up there or something in the future, the cable would be useful for that even if I never really use the iMac.

Captain America: The Winter Soldier has come out on DVD / Blu-Ray in the UK, I think a few days ahead of schedule. Does anyone know how the extras compare?
