Of course it does, you just have to use a VC-1 interlaced compatible DXVA codec, like ArcSoft or Cyberlink.

For a pure HTPC, those extra cores don't do anything. Full deinterlacing and scaling don't even make a GTS 450 sweat at normal playback speeds. Once you start benchmarking, you'll hit the performance limit at around 100 fps deinterlacing performance.
There is no advantage in getting a 460. The 450 is a scaled down 460, there are models that are equally silent (mine is perfectly silent, i dont hear a thing), and use less power then a 460.
For pure decoding and post-processing, a 450 is plenty fast, and any more is overkill. Only if you ever plan to game, the upgrade may make sense. I have no experience with a 440, but the GDDR5 version should probably also be fast enough.
I still want a 520 with some more 3D performance, at least at the level of a 440.
