The only UK UMD movie I have is Cowboy Bebop, because it was in a closing down sale and pretty much the only anime the store had.
There are actually some quite cheap anime UMDs in Japan - I got Amuri in Star Ocean on UMD since I was sort of interested in it, but not enough to shell out for the three DVDs.
The Bandai Visual blu-ray discs were all printed in Japan for sale here, there and in the US, so the discs all had BBFC logos screenprinted onto them and frontloaded FBI warning screens. The only difference was the piece of
paper inserted under the shrinkwrap. I assume the DVDs are a little different due to video formats. I have Patlabor as I found it going cheap, but it had been out for ages so never made any comparison with the other version or entered into any discussion about it.

The Blu-Ray Blues article which sums up BVUSA pretty well:
Because, you see, now we can fit 30 languages on a single disc, it makes sense for it to be a single release, mastered in Japan. In theory, this is great news for anime. In practise, however, right now there are a dozen people in Tokyo offices saying that foreigners are stupid and don’t know how to sell anime.
