I've spent some time reading about how deinterlacing works and from what I have come to understand that with modern cards, it is done at the hardware level and you can configure it in Catalyst Control Center. There are several deinterlacing modes like bob, weave, vector adaptive etc, with vector adaptive being the best. So this tells me that if my video card and its drivers are doing this, then the stream should look the same (as far as deinterlacing goes) in any software player.... but it doesn't.

I downloaded the cheese slice 1080i mpeg2 file that Anandtech uses to test video cards, and with vector adaptive deinterlacing enabled, the cheese slices look fantastic in Power DVD8, but in VLC player and Media Player Classic, the cheese slices look AWFUL... really bad diagonal lines. How can this be? If the video card is performing the deinterlacing, why would it look different in one player vs another?
