.ra (old Realaudio format) is not supported at the moment (both streams 
and files), just like the old codecs 14.4 and 28.8 they usually use. If 
you have files with .ra extension but rm format, please tell me and 
i'll add them. Anyway, i think .ra files are streamed with pnm:// urls. 
Do you know any rtsp url that streams an ra file?

What kind of files can be received with live.com libraries? Is it 
possible to stream .rm files with standard rtsp protocol? If yes, the 
extension detection needs to be fixed.

I'd also like to remove the extension detection system, but i don't 
like the idea of trying every protocol (Real, live.com, and maybe more 
if other companies will implement their own variation of rtsp) until 
one succedes. Is it possible to send a very simple query to a rtsp 
server (i mean: open a port, send a string and  get a short, simply 
parseable answer) to find out its manufacturer or other unique 
identification?
