Hi Nikola,
Thanks again! That works but if I move my hand by the camera, there is latency before I see it on the gst-launch-0.10 playback screen, and when my hand moves it moves really fast when it shows up.
Are there any other tricks you might know of? Again it works perfectly at 10kbps when I have gst-launch playbin uri=rtsp://192.168.0.90/mpeg4/media.amp
running.
Thanks -tom

Try "xvimagesink sync=false" should do the work,
