Thanks for the fix.

Unfortunately it do not solve the bug for me. My client (gstreamer
0.10.31) do not start to recive RTP packages before receiving the RTSP
OK message, send in reply to the RTSP PLAY. The new relased 0.66
windows Media server sends the first RTP packacket before the RTSP OK,
the 0.65 linux version sends the first RTP package after the RTSP OK.
This behavior is consistence and seen in several net-dumps. Dump of
some selected lines in wireshark using windows and then linux Media
server below.
