We are attempting to stream MP4 through an ASA 5520 running version 8.1. The RTSP handshake takes place and I can see the teardown when the connection is terminated, but the files themselves never show up at the end device. I don't see any blocking messages. This same stream works fine if sent to a device that is not behind the firewall.
Any ideas what can be happening?

Hmm, what interface are you trying it from? Can you plug in a PC into an open test interface and try the transfer from there?

It's from the 156.74.104.5 interface. I don't have physical access to this device, which makes it difficult to attempt a direct connection.

Also if it a 5520 check if it has a CSC module in it and if the module is blocking streaming media.
I hope it helps.
