Is there a better method? I ready about querying latency, but that seems to be worse case latency, not the value at a given instance. </BLOCKQUOTE> I think the effective latency between A and B, is the difference between the time of the buffer the comes in A, and the one going out of B. If B is a sink, you can just convert you buffer time into stream time, and query the position from the sink. Though I never got into testing that idea. Nicolas </BODY> </HTML>
