I just noted that Kaffeine loads media:/ urls as local files (just well), but doesn't do the same with system:/media/ urls.

So I changed a bit the file src/playlist.cpp:

*** playlist.cpp        2005-10-26 15:10:33.000000000 +0200
--- playlist.cpp.new    2005-11-02 14:44:23.000000000 +0100

        {
                mrl = MRL(urls[i]);

!               if (mrl.kurl().protocol() == "media")
                {
-                       QString url(mrl.kurl().prettyURL());
                        QString mediaName(url.mid(7));
                        int slash = mediaName.find("/");
                        QString filePath(mediaName.mid(slash));

        {
                mrl = MRL(urls[i]);

!               QString url(mrl.kurl().prettyURL());
!               if (url.startsWith("system:/media/"))
!                       url.replace(QRegExp("^system:/media/"),"media:/");
!
!               if (url.startsWith("media:/"))
                {
                        QString mediaName(url.mid(7));
                        int slash = mediaName.find("/");
                        QString filePath(mediaName.mid(slash));


Simply if the url start with "system:/media/", change it with "media:/"; then if the url starts with "media:/", continue normally.

It works perfectly in my system.

I hope this will help ;)

Thank you and good bye
