It looks like you are releasing the references properly, but in general
I would strongly recommend using CComPtr and CComQIPtr. Then you won't
have to worry about releasing anything, it's done automatically.

What kind of file are you trying to play? The memory leak might be in a
decompressor or another filter that's inserted into the graph.
