"vlc" does, indeed implement RFC 3640 (and many other RTP payload formats), 
through it's use of the "LIVE.COM Streaming Media" code 
<http://www.live.com/liveMedia/> for playing RTSP/RTP streams.

*However*, RFC 3640 is *not* the answer to the original question.  RFC 3640 
describes how to encapsulate MPEG-4 video in RTP packets.  It does not 
describe how to encapsulate MPEG-4 video within a MPEG-2 Transport Stream.

I don't know whether such a thing is possible, but if it is, it will 
probably be defined by a MPEG document, not by an IETF RFC.
