Which browser are you using? You can get the Media Player Connectivity extension for Firefox at https://addons.mozilla.org/extension...nfo.php?id=446
, just be careful which one you install; my version of Firefox on XandrOS 3.02 OCE needed an old version or it breaks the browser. I used 4.6.1 ...
Then: Since you're running a Debian distro, add
to your /etc/apt/sources.list file, and run
apt-get install w32codecs
as root. It will create a /win32 directory in /usr/libs, which should contain all the codecs you need to play these files, as well as QuickTime.
Hope this helps ... this worked in XandrOS 3.02 OCE.
