the mplayer on my linux desktop (fedora) can play media files in all kinds of codec, but it isn't the case on the N900. i've tried copying the codec files downloaded from the mplayer home page to /usr/lib/codecs (like the setup on fedora) but it doesn't work too. however, the media player (with the extra codecs installed from the maemo repository) on the N900 can handle those files that mplayer cannot. is there a way to link those codecs to mplayer?
