Is your source data a MPEG Program Stream, or a MPEG Transport Stream?

Do you get the same problem if you create a new file by concatenating 
together two or more copies of the original file, and then stream 
directly from this new file (rather than from stdin), using the 
original, unmodified "testOnDemandRTSPServer"?
