[sip-comm] No video is displayed for movie file


Hi freinds,
  I am running SIP_communicator on 2 windows 2000 machines and running the SER server on a Linux machine. All three machines are on the same LAN. I have disabled STUN. I am able to dial up the other machine and audio conversation between them is possible. Since I dont have a web cam right now, my sip-communicator.xml file has the following entry

<MEDIA_SOURCE value="file://E:/SIP/lostinspace.7.160x120.11khz.mov"/>

<MEDIA_BUFFER_LENGTH value="100"/>

<IP_ADDRESS value=""/>

<AUDIO_PORT value=""/>

<VIDEO_PORT value=""/>

The other party is able to hear only the audio but no video

Can anybody please help
