I have retested it and now is quite different:
sometimes everything is black with no output (with no network activity)
some other times the error message is
Totem could not play 'mmsh://live.mediaserver.kataweb.it/retea?MSWMExt=.asf'.
Could not open location; You may not have permission to open the file.
