Probably not if the input data is coming from a RTP (or even raw UDP) 
source, because in this case the input Transport Stream data is 
supposed to contain an integral number of 188-byte Transport Packets 
(and therefore start with a sync byte).

However, inserting a "MPEG2TransportStreamFramer" wouldn't hurt, I suppose...
