I've tried playing all the medias using 
libvlc_media_player_new_from_media (thus creating a new media player for 
every media in my playlist) and this times seems to work, except that 
the previous media remains (do i have to force a stop?) and a new 
windows for media reproduction is opened.
Is this the correct behaviour or can i reuse the same media_player for 
all my playlist?
