Hudson Hawk: German vs Italian BD

[Funktion]

I'm looking to add Hudson Hawk to my collection.

There's two region B releases available, both by Sony, one in Germany, and one in Italy, with the later being cheaper than the former. Judging from the back covers, both releases feature the exact same content, and the exact same audio and subtitle options, even the covers and back covers are pretty much a match, but this website lists the German release as BD-50, and the Italian release as BD-25.

To make matters a bit more confusing, I've seen German websites listing the German BD both as BD-25 (http://www.bluray-disc.de/blu-ray-fi...b-blu-ray-disc) and as BD-50 (http://www.cinefacts.de/DVD-Blu-ray/...21735620,80181).
Has anyone checked any of the two releases, and could confirm if by any chance the listings on this website are incorrect, and indeed the two releases are identical and the German release is a BD-25, or the Italian release is a BD-50?
