If a cyberlink decoder is present in the system in which i have

I founf that my filter is getting connected with Cyberlink decoder.
But if cyberlink decoder is removed, then my Filter refuses to connect
with the default MPEG2 Video Decoder present in Vista (Microsoft MPEG2
Video Decoder).

So the following may apply to the MPEG2 decode in Vista:

Some MPEG-2 decoders will only connect with a specific renderer (example
VMR7 or VMR9) to prevent grabbing of frames.

Also, some may insist on connecting to renderers that support
VIDEOINFOHEADER2 for deinterlacing.
