con totem esce invece questo msg:

Totem could not play 'mms://media.fastweb.it/WM9/raiclick/FMVRAI04000001056261.wmv?idCnt=31063&path=Home¿Not izie¿ARCHIVIO¿BALLARO'#1'.
Video codec 'MS WMV 9 (win32)' is not handled. You might need to install additional plugins to be able to play some types of movies

insomma... cosa manca???
