as everyone knows that's Tried to work with AMD you cant even get them to provide the Linux Open Decode library to go with the SDK, or even get simple and reported AMD driver bugs fixed in a timely manor.
so no reliable HW decode across the 3 versions of the broken DRM/UVD ASIC from even the one 3rd party Linux dev that did sign the NDA, and he's all but given up on them now, and who could blame him, AMD just dont want to play ball never mind be in the game it seems.

It's sad that AMD missed those wide spreading opportunity early on (imho it was a bad mistake) though i remember when i made Donald aware that he could utilize Nvidias DSP back then under Win32/64 utilizing their SDK @ that time Nvidia didn't released the Linux part of it either it came later as the whole concept of VDPAU slowly emerged, though they still haven't open the Encoder part for Linux yet nvcuvenc api which they have done for Win32/64 since some SDKs back now.
The overall response to opening the Encoder (Opening means in that sense setting the API free from NDA barriers, though it seems they where internaly discussions about a entirely Open Source GPU Encoder based on their Research, maybe that idea didn't died fully yet,though you don't have to forget the ISVs making business with their closed Encoders now such a project could hurt in some ways and be helpful in others depending on your customer base) was the same as back then with the Decoder in some weeks a lot of even no name Applications (not always good ones though but do they need really to care about that ?) adopted it in no time (also because their excellent support and documentation) (not only the big ISVs had now access after some short ISV NDA exclusive time) and that's the Power of their Ecosystem (Donald and the Doom9 Community helped a lot Debugging VPx in the same way which helped improving the Quality for every Application and for every user involved in the Ecosystem) though it seems AMD cared more about exclusive stuff and keeping it down to a minimum ISVs @ first (for a very long time) and for Linux it seems even heavier restricted.
I can mostly only speak about Nvidia and they did everything right from the first day strategy wise without hurting the business aspects to much (on the Desktop) and Utilized the Power of the Community as best as possible (with braking down the NDA ISV barriers really fast without hurting anyone else to much and also seeing more the mostly positive things then negative ones that would arise from that "Openness" i can only congratulate the brain behind this decissions @ Nvidia) which in the end made everyone happy and be part of that Software/Hardware Ecosystem
(ISVs,Consumer,non ISV Developers,Geeks)
AMD reacted a little slow (and the hell its absolute sad seeing that they have the more Powerful Hardware @ Hand also because many Developer made them aware that it would be good to have that support and saw the demand from users for it early on as Nvidia came up with it,on the other side most resources where going @ that time into Fusion and how to integrate ATI efficiently as possible into their future concept), its almost predictable that Fusion would have a much better adoption rate with such a "Open" available Ecosystem to mostly everyone and we can see AMD is trying to speed up their now again at least on the Win32/64 side finally, it's sad for the Linux part though and that Nvidia is still much stronger their in terms of overall Developer support as you explained it.
Btw everyone of the
P67 Board buyers forget what reviews are telling you that Intels QuickSync would never work if a discrete GPU is being used that is not true it is either a Bios Restriction or a a Software lock on the OS Driver level but not has anything todo with a Chipset Hardware limitation thing.
Intel is doing since several years now allot on Software Restriction research @ their Hardware level they started this with making several things remotely available last year via a service call on their Motherboards and even the lower price Pentium Chips (upgrade it via a call to a higher series no problem). The same they did this time on the
P67 series of Boards see this proof talk by some Intel guy
http://www.youtube.com/watch?v=gui_6sNc7Eo
Intel is fully in the concept of DRMing their Hardware for Business purposes now, so yes who knows how its working on the Chip site and if the same Series is restricted the same way by a clever combination of Bios,Key,Motherboard and Operating System the same as they bringing in TPM now to finally make Hollywood being able to provide full 1080p experience On Demand and without any time differences to a Cinema release, as they feel save now with Microsoft and Intels TPM Ecosystem (we will see how long that holds up though)
Please also keep in mind i don't say its possible without this Lucid Virtu (Framebuffer copying under Vista/Win7 very efficiently doable as everything is on the GPU already though this most probably highers latency some ms again especial in Windows mode like shown in that Video so Gamers or people who think of Multi GPU data Displaying should be careful, though it is cool and indeed a dream i guess of everyone in the Consumer level to see that) to actually use both Discrete GPU/CPU together @ the same time that obviously isn't possible physically by the Hardware itself it's just the fact that their Software can see the QuickSync that makes it invalid that the P67 turns everything of via the Hardware, but Intels Software layer (Bios/OS Driver) is actually doing that and Lucid got the Permission to disable it to be able todo what you see inside that Video
or the other Logic assumption would be the Intel guy is actually mixing up stuff here (mixing up H67 with
P67 though several times repeatedly) and all the reviewers like Anandtech are correct if they say
P67 doesn't support the Intel QuickSync GPU feature @ all (the information they get from intel and all believe to be true, the motto being better don't think believe everything my partner tells me and put that into public) you decide what is the truth
Now to make it even more Confusing

To demonstrate the technology Intel ran an H67 motherboard with a GeForce GTX 480. Lucid’s software was installed which allowed for the GTX 480 to run and its frame buffer output to be copied to main memory and sent out via Intel’s Flexible Display Interface through the DVI port on the back of the motherboard.
