That should not be the case.  If you use the 
"testMPEG1or2AudioVideoStreamer" demo application (and enable the 
built-in RTSP server), or the "testOnDemandRTSPServer" application 
(using a Program Stream file named "test.mpg"), or the 
"live555MediaServer" application (using a Program Stream file named 
"<anything>.mpg"), then VLC should be able to play both the audio and 
video streams.

Because VLC does not implement that RTP payload format.  (Nor does 
anyone else; instead, everyone streams MPEG Program Stream data as 
separate audio and video RTP streams.  You should do the same, using 
the supplied demo applications as a guide.)
