EDIT: Not to derail this thread too much but does anyone know if the UK Dawn of the Dead Blu-Ray looks superior to the US one?

This is not derailing, this thread is about different region DVD's and Blu-ray's not in the US, but to answer your question, they are both MPEG-4 AVC encoded, but the UK is not OAR, it is 1.78:1 where the US version is OAR of 1.85:1, the UK has DTS-HD MA 5.1 audio, but the US has LPCM 5.1 audio and original mono, UK does not have the mono, but the UK version has a bunch of goodies on 2 DVD's, I think that is where the UK version beats the US version, but video to video, I like my US version.

Actually I have been doing some investigating into this UK version, the Theatrical release is the Blu-ray, the Argento version is on 1 of the SD DVD's, so I will definitely not be getting this, I already have ALL versions on DVD in the huge Dawn of The Dead Ultimate Edition with boatloads of extras.
