Re: QuickTime and SMIL

Sarah-

Both video and captions work fine for me on Windows XP in both
Netscape 7 and IE6. However, if the client is not capable of receiving
video streams through the rtsp port 554, then it doesn't work. This is
commonly caused if the user uses proxy servers or firewalls that
restrict rtsp data. You can fix this by setting your Quicktime server
to allow streaming on port 80. This will fix the problem for just
about everyone, even if they have a firewall. Unfortunately, this only
works if the Quicktime server is not acting as a Web server (which
also uses port 80) and I noticed that your QT server has Apache Web
server installed. For this to work, you will have to turn off Apache
or change the port that it uses.

It seems to me that the problem does not lie in your SMIL, but in the
ability for your QT streams to bypass firewalls and proxies.

Nice video, by the way.
