So it seems the ideal media player has yet to be developed. Xine would not open the particular url. I got the latest gxine from slackware and it is playing what I want well. Realplayer doe it too, however, the streaming is bad. In both, realplayer and gxine I can start playing video urls from the playlist. Totem does this not, etc, etc. So each player has its own peculiarities. Good that there is a choice, guess thanks to Linux.
