Hi,
This is quite important, can you please expose the same sub-types as other existing filters?

For example, after registering the filter, trying to play an AVI file with XVID video and MP3 audio fails using the standard microsoft AVI splitter as the "file source (async)" filter exposes a different sub-type.
This behavior breaks compatibility with players that rely on the filter's sub-type to identify media formats and breaks support for existing filters that rely on these sub-types for the same purpose.
