When I try to view a quicktime movie in VLC, I see the video just fine, but I don't get any sound. The debug window shows this:
[00000243] logger interface: VLC media player - version 0.8.0-test2 Janus - (c)
1996-2004 VideoLAN
[00000243] logger interface:
Warning: if you can't access the GUI anymore, open a dos command box, go to the
directory where you installed VLC and run "vlc -I wxwin"
[00000243] logger interface: Using the logger interface module...
[00000282] quicktime decoder error: cannot initialize QT
[00000282] main decoder error: no suitable decoder module for fourcc `QDM2'.
VLC probably does not support this sound or video format.
Let me know if you need any more info.
