I would argue that it's worth it for SD as well as HD, the better quality 
de-interlacers alone make it worthwhile, especially since VDPAU-capable video 
cards are pretty reasonably priced.

Unless, of course, you have an AGP system, no VDPAU cards seem to be available 
with that interface. Is it worthwhile to replace an entire system? That I 
can't answer, of course. It is for me, but assuredly not for some others.
