installer mplayer sous debian (autre question)

[Tiago Saboga <tiagosaboga@terra.com.br>]

Et bien, je profite de la question pour en poser une autre:

Comment installer les codecs pour voir des videos stream en format rm (je les 
vois actuellement avec real player, mais c'est pas libre...)?

Quand je lance mplayer (j'ai installé mplayer-k6 de marillat), j'ai le 
résultat suivant:

J'ai cherché dans les docs, mais j'ai pas été capable de découvrir quoi faire. 
Toute indication sera bienvenue (même un RTFM, si on m'indique le manuel ;-)
