Hope I've got the right end of the horse here, it's going back a bit ..
We ran a realserver for a fair while, while there was a 'stable' FreeBSD
binary anyway, and for way too long after, on a dinky 56k modem link :)
Apart from over HTTP,
rtsp 554/tcp #Real Time Stream Control Protocol
rtsp 554/udp #Real Time Stream Control Protocol
and you'll already know about
appleqtc 458/tcp #apple quick time
appleqtc 458/udp #apple quick time
and (consulting an old stateless firewall) realplayer by default used
sometimes 6970-6973? but the default 7070-7073 UDP main port and range,
and most of (clients' and ISP's) firewalls will let these pass.
I seem to recall quicktime (audio anyway) could/did allow/suggest at
least one of those UDP ranges also (because ISPs commonly let it flow),
but I could easily be forgetting what was when and who did what to whom.
I see my Billion ADSL router by default allows 7070 in and out, labelled
'_rav' on 'medium' security level, so that's the commonest default port,
but as I said, this is dredging up the past .. I've done no video stuff.

No idea ..
HTH (but I doubt it :)
