[ACCELERANTS] Intel SandyBridge
It would be great to have a hardware-accelerated optimizations support for SB too.
Here's the (open source) FFDShow-related project: Intel SandyBridge hardware accelerated FFDShow decoder (H264/VC1/MPEG2)
Dunno if this can help in any way, but i believe that the author (Eric Gur, Processor Client Application Engineer @ Intel Corp.) could be also involved.

Fortunately for owners of Sandy Bridge based systems, haiku's full time contract programmer Michael Lotz recently acquired a Sandy Bridge based laptop with which he does his haiku work. As a result we should eventually see some good compatibility with Sandy Bridge based systems. See

But I suppose I've to use plural as all Haiku dev are "massives" so:
You're massive men, I'm intimidated by you :-) !
