The german Star Wars PAL DVDs are not pitch-corrected. Means, the sound is faster and the voices higher.
I know exactly, because I added the german GOUT soundfile to Harmys Despecialized Empire and had to slow it down for 24p. After that it had the right pitch and I probably heard the german voices the way they were heard at the cinemas for the first time.. (well, ok.. I watched the special editions in the cinema in 1997, so let's say for the second time ;)
