RTSP streaming Flash lite 2 application error

Question

I'm developing a RTSP streaming Flash lite 2 application. I'm streaming to drawing server by VLC (port 554) vlc -vvv /video.flv --sout "#transcode{vcodec=h264,vb=360,fps=25,scale=0,acod ec=mp4a,ab=128,channels=2,samplerate=44100}:rtp{ds t=127.0.0.1,port=5004,sdp=file:///C:/Darwin Streaming Server/Movies/myStream.sdp}"

When I tried the application the emulator it worked fine, but on my E71 I got this error "error preparing video for playing". I tried to connect to the server by realplayer, but I had this error message "not enough bandwidth", although I could stream BBC RTSP URL .

I'm using my own server, and it has a static IP.
