An update on the problem that Francisco Leon noticed (failure to play an URL beginning "rtsp://start.real.com/"). The problem here is that this RealNetworks server behaves differently, depending on whether or not the client is one of theirs. (It makes this determination based on a "ClientID:" RTSP header.) If the client is not one of theirs (which is the case for "MPlayer"), this server fails to complete the RTSP transaction (in a non-standard way, but I digress...). If the client is one of theirs, this server sends back a "302 Temporary Relocation" response, redirecting the client to a "http://" URL, which MPlayer would be unable to handle anyway. (Also, the "http://" URL points to content that's encoded in SMIL, not HTML.) In any case, MPlayer would not be able to play the stream, because it apparently requires paid membership in "RealOne SuperPass" or "CNN NewsPass". Ross.
