Stops because it thinks it has reached the end of Stream.

I found the code where the errors are printed in libmpdemux/realrtsp/real.c
function int real_get_rdt_chunk(rtsp_t *rtsp_session, char **buffer) 

here we attempt to read 8 bytes (RDT chunk header) from stream

n=rtsp_read_data(rtsp_session, header, 8);

  if (n<8) return 0;
  if (header[0] != 0x24)
  {
    printf("rdt chunk not recognized: got 0x%02x\n", header[0]);
    return 0; 
  }

added some more debugging to get this output when running sample stream
rtsp://mms.sonix.de/universal/rock/apocalyptica_lifeburns_300.rm?start=60

rdt chunk not recognized: got 0x4f 
hexdump> 4f50 5449 4f4e 5320  or OPTIONS{SP} where {SP} is space character
 
rdt chunk not recognized: got 0x2a 
hexdump> 2a20 5254 5350 2f31 or * RTSP/1

Think the issue could be receipt of a packet from the server which is not RDT
but RTSP at which point processing the stream fails shortly afterwards.

Hope this might help someone debug further.
