Does anyone know some detail about the WMP statistic network.Bandwidth. I am using the WMP ActiveX in a service quality measurement project for streaming and progressive download. This statistic is described as "the current bandwidth of the clip" in MSDN documentation. I don't understand that. Is it the rate at which the playback data is read from the network? Or the rate at which data is playing? When compared to the data received on a network interface card dedicated to the media stream it is largely similar over time, but when sampled on a per second basis the data rate on the NIC (measured with iphelper GetIfEntry() dwInOctets) is much more volatile. Under very adverse network conditions where network responses are delayed by several seconds but not long enough to timeout, then when sampling network.Bandwidth every second it "sticks" at the last recorded value, even though simultaneous monitoring of the network interface itself shows that the bit rate has dropped to zero. Does it only re-populate this statistic when a network read completes? This makes it difficult to use on a sampling basis as it will overestimate the data arrival on a network with problems. It would be very useful for me to know how the statistic is measured and the rate calculated. Thanks -- Joe Walker Developer, EPS Ltd
