Capture of RTSP connection (with server IP hidden)

I have a RTSP server in a PAL encoder that is set up to only broadcasts using multicast. However the gstreamer client still tries to listen to unicast.

I cloned the git repositories, compiled it and tested to see the bug is still with these (as specified by git describe command)

gst-plugins-base RELEASE-0.10.30-383-g1469453
gst-plugins-good RELEASE-0.10.25-263-g5b68b64
gstreamer RELEASE-0.10.30-292-gb804d53

Attached is the network capture of the RTSP TCP connection I took using Wireshark. The conversation was started using command gst-launch -v rtsp://n.n.n.n:7070/ ! fakesink.
