    initial v1  
    22> Can anyone come up with a better sniffer rule? It looks like after that first sync byte, there isn't much to analyze (s. [http://en.wikipedia.org/wiki/MPEG_transport_stream#Packet wikipedia]), or is there?

    4 Our sniffer rule syntax don't support a repeat mode, otherwise a way better rule for MPEG files would be simply to check the sync 0x47 ('G') byte every 188 bytes, not just first one.
