QuickTime force TCP Transport - Firewall Issue



I have discovered what I think is another undocumented "feature" of QuickTime player.

I notice that on certain firewalls, namely a Netgear FVL328, that the QuickTime auto transport negotiation will fail to connect to a normal UDP RTSP stream, unless you force the Network Transport to UDP. However, if you specify the port in the URL, i.e., rtsp://127.0.0.1:554/test.sdp, this seems to force the player into Interleaved TCP mode which QTSS/DSS also supports. This works fine.

The question is, can anyone verify this with the developers and ask if this is documented anywhere?

BTW: This behavior is noticed using the latest QuickTime player 6.5.2 on WindowsXP SP-1.

Thanks.
-greg.
