You can now install VLC Player in your Nokia N900, just download the application from here, save them, for example, in / home / user / MyDocs:

libvlc5_1.1.0~git5935-1_armel.deb
vlc-nox_1.1.0~git5935-1_armel.deb
vlc-player-nox_1.1.0~git5935-1_armel.deb
vlc-player_1.1.0~git5935-1_armel.deb

* install the 4 above, in the same order, for this type:

dpkg-i /ruta_al_ archivo / filename.deb

Now we can run VLC, type:

vlc /ruta_al_archivo

ie,

vlc /home/user/MyDocs/archivo.avi
