Hi, I downloaded the "Large" guided tour for the MacBook Air from the Apple website:
http://movies.apple.com/movies/us/apple/mac/macbookair/2008/apple ... 48x528.zip

It's a 184MB MOV file. When I try to play it with Quicktime Player it shows video but no audio. Just to discard problems with my Quicktime Player I upgraded to the latest version (v7.4 with latest updates) and downloaded other MOV files to test and it plays them fine with both audio and video, so the problem seems to be with this file alone. Mediainfo shows the details attached below for the file. Anyone can provide a clue as to what's causing this? Thanks.
