A follow-up to your previous message: You *can* disable RTSP if, instead, you have VLC open a SDP-format (i.e., ".sdp") file that describes the PCM RTP multicast stream. You can get a SDP description for the stream by running the "openRTSP" tool on the "rtsp://" URL. Ross Finlayson LIVE.COM <http://www.live.com/>
