In Nokia 3650, RealOnePlayer can only be used to real streaming.
But 6600 support both real streaming and 3gpp streaming.
There are two player on 6600: real player and nokia player.
Which one support 3gpp streaming? real player or nokia player?
It seems that the URL like "rtsp://hostIPort" is not supportted, it is necessary to include a file name like "/x.rm" to be supportted by RealOnePlayer on 6600.
Even if the URL with no file name can be accessed by RealOnePlayer 2.0 on PC.
