Differences between UK/US Blus?

[Bk_Tan]

I was specifically referring to Pirates of the Caribbean which apparently has less special features than the US counterpart but also that it is the policy of Disney to do this.

Are many of the releases like this, features being stripped for no apparent reason either than the fact it's a different country?



As a side note, I was looking for DVDs and found that the Pirates of the Caribbean UK box set has only 4 discs whilst the US one has 6, so has the UK/Region B been sidelined throughout history?

Reposting here because I'd hopefully get a quick answer.
