OK.

What version of Windows is this? Can you send traces?

Yes, after we send a “KSEVENT_PINCAPS_FORMATCHANGE” event, our call back get 
called to tell us that the format has changed. (We are setting a breakpoint in 
our event handler to check this.)
We would expect “NewStream” to be called to test what format we now support, 
but this never happens.

Thanks,
Paul
