And once again. "H.264" is NOT an example of an alternate stream. An example of
an alternate stream might be QuickTime, Real Media, or Windows Media, but not
"H.264." H.264 is merely the compression algorithm used in creating the payload
of the IP packets generated by any of these options. By itself, "H.264" it DOES
NOT define the stream, Craig.

Once again. There is no "H.264 version." H.264 is used by Flash and by
Quicktime, and by any player that also supports RTP/RTSP. How is it you think
H.264 defines the streaming protocol, Craig? I think this is the source of a
lot of confusion on your part.
