Playing a video (mkv, avi,...) that is served via the MP2 Server and not on the local PC currently requires the MP2 Client to mount the resource with Dokan, because standard directshow source filters available on Windows need a file path as input.
We can skip this additional step (and overhead) by directly playing the System.IO.Stream that the Resource provides when using a directshow source filter that accepts a System.IO.Stream as source.
