    I build the sample(avstream) in wdk directory.Unfortunately i find that if rendering the driver in
    graphedit twice at one time, the second object in the graphedit can not play. There is a alert dialog, "another application is using this file, return code:0x80070020".
    The avstream minidriver could not be opened twice at the same time?

    thanks in advance
