It played on Itunes, just took an eternity to load. it won't play on VLC or any external player which royally pisses me off, unless i pay about 60 quid for a program to convert it from mv4
Apple content is protected by fairplay 3 drm, you can't play it on non apple platforms so no vlc or mpc-hc etc. You can remove it but it depends how good you are with this stuff.
As TC says it's protected by DRM mate, the best thing to do would just be to download the movie drm free (wink wink) and play it in vlc
There are usually places (wink wink) you can download web rips that don't have drm plastered all over it
I managed to get hold of the full bluray but you probably won't see it publicly everywhere for a few days, or encodes from it.
