I bought the German DVD back before Christmas, and still haven't had a chance to check it out (or compare it to Dark Jedi's downconversion of the HDTV broadcast).
There has since been a UK Region 2 release as well. According to dvdcompare, the English track on the German DVD is dual mono instead of Dolby 2.0 Surround (which the UK release has). I haven't confirmed this yet.
