I see. In testMPEG2TransportStreamer the MPEG-TS is streamed using  
RTP. Doesn't RTP cover the same issues as MPEG-TS when it comes to  
synchonisation and overcoming data loss?
I know it still doesn't make a good case for a transport stream  
demultiplexor in a streaming library.

Thanks for your input
