I heard that there was a fixed GOUT disc available with corrected audio?

The German audio track was faulty on some discs. In chapter 13 of ANH when Luke, Han & Chewie wait for the elevator to the detention area, the announcements in the background are missing - as well as the lines "Ich kann in diesem Helm überhaupt nichts sehen (I can't see a thing in this helmet)", "Das wird nicht funktionieren (This is not gonna work)", "Warum hast du das nicht gleich gesagt? (Why didn't you say so before?)" and "Ich habe es gesagt (I did say so before)". A replacement disc with fixed German audio is available from 20th Century Fox Home Entertainmemt by emailing info@tcfhe.de.

If you reverse the PAL audio speed up you will get a slower (deeper) voice of everybody, which doesn't feature the original voice frequencies.

Surely the original dub was for the film's theatrical presentation, and so would be at film speed? The voices would therefore be sped up (higher pitched) for the PAL DVD; slowing down should restore the original pitch.
