FYI, I have installed several hinted H.264 ".mp4" files (from Erik) in a 
Darwin Streaming Server running at our site.  For the next few days, you'll 
be able to access these as
         rtsp://ns.live.com/X
where "X" is one of:
         fm_1400b.mp4
         fm_cif_198.mp4
         fm_cif_base_15i_1400b.mp4
         fm_cif_base_99_15i.mp4
         fm_cif_base_99_15i_2.mp4
         fm_cif_base_99_nostap.mp4
         fm_cif_base_99slice.mp4
         fm_cif_base_std.mp4
         foreman_cif_30i.mp4
         foreman_cif_base_9.4.mp4
         foreman_cif_test.mp4
         forman_base_30I.mp4
         lang.mp4
         trevor_176x144_150_baseline.mp4

Erik, is this still the case?  (I haven't looked at your 
"H264VideoRTPSource" code in detail.)

Erik, how big are your changes to "livedotcom.cpp"?  Let's see if we can 
work this out.

Yes, that's a good idea.  I'll look into this for a future release.

         Ross.
