There seem to be two different German DVDs (well, three, if I count the Renegade Version in a Highlander 4 Movie Box, that only has german subtitles, and was as add on to the Highlight DVD Version in that box), if I read the ofdb.de Information correct.

One with German 5.1 and 2.0 Audio and Running Times: 93:35 Min. (88:41 Min. w/o Endcredits) from Arcade Video/ Highlight

The other with German 5.1 Audio and Running Times: 95:56 Min. (91:04 Min. w/o Endcredits) from Concorde

Maybe the Concorde release is the same Version as the Italian release. (The italian VHS is stated to have a running Time of 96:10 Min. With studio logos and such it could fit to the Concorde DVD release...
