RTSP seeking failure with Darwin Streaming Server

I am trying to use VLC (2.0.7) on windows environment to play a video file. This file is streamed from Darwin Streaming Server (6.0.3/Linux).

I use this URL pattern to test : rtsp://myserver/movie.mp4.

Play, pause and stop work perfectly. But when i seek 30 seconds forward, VLC plays 2 or 3 seconds and blocks during 30 seconds. If i seek 50 seconds forward, VLC plays 2 or 3 secondes and blocks during 50 seconds. After this blocking duration, VLC plays correctly but slider position doesn't correspond to video position.

I analyse network trafic and when i seek forward, VLC sends rtsp "play" command correctly; Darwin seeks in correct position and sends RTP packets correctly too. I could check VLC blocks receiving RTCP "SR" packet from Darwin. With a firewall, if i block RTCP packets from Darwin to VLC, forward seeks work perflectly (backward don't). VLC appears to not synchronize correctly internal clock from RTCP packet and rejects RTP packets during seek time duration.

When VLC is blocked during seek time, console displays this :

Seeking backward doesn't work too.

With other player (quick time, ffplay, etc.). All works fine.
