Mumble...  When streaming from a Transport Stream source, our server code does not change the contents of the Transport Stream input data at all (except when doing a 'fast forward' or 'reverse play').  It just copies each of the 188-byte Transport Stream packets into outgoing RTP packets 'as is'.  That's why you'll usually see a discontinuity in the 4-bit "continuity_counter" value after a seek.  I don't plan on changing this, unless it causes a major problem (which it sounds like it doesn't).
