I only got my hands on a deluxe copy yesterday (had to order it in) and just stuck the DVD into my laptop... it is registering as Region 4 PAL. Hit change region code button just to see what would come up and sure enough - it came up as Region 4.
Positive proof now that it is definitely without a single doubt, a regional code problem and not an PAL/NTSC problem.
BTW: The Blu-ray shows not a sign of Region B restrictions (and my Bond 007 movies that are Blu-ray are restricted and they also have a dirty big "B" written across them).
Yes, people can use this post of mine as ammo to fight back with as far as Getmusic is concerned (I am in Australia) but remember, hounding Getmusic with emails at this time of year can only make the situation worse so give them a bit more time.
