Does UVD work with Vista 64-bit yet?

When I play a blu-ray on my 3850, I always get around 50% cpu usage and 1% gpu usage. I've been trying to figure why UVD isn't working and I read an article from July 07 that says that uvd doesn't support 64-bit vista. I'm using the latest powerdvd patch and catalyst 8.2.

If this is still true, it's BS. I have to use Vista rather than XP if I want the latest gaming features, I have to use Vista 64-bit if I want to use all of my ram, and I have to use 32 bit vista if I want to watch blu-rays.
 
if you have a decent CPU you dont need UVD, not that it's ok for it to not be working, i think thats bullocks too, but still, not being able to use UVD doesnt mean you cant watch HD content unless the rest of the system is anemic, and assuming you are running 64bit Vista Ult, i know thats not the case

Well UVD is the reason I bought a 3850..

ok...i agree, so this is more of a point in making sure a feature is working as it should rather than a problem issue, UVD is ONE of the reasons i steered a friend to a 2600XT for his HTPC build last year, i could not tell you if it is working or not, he is also running Vista Ult 64bit, i will have to ask him

how do you even check to see if it is active and working? i run a NV card so i would not know
 
CPU usage can be seen in the task manager; it should be around 10-20% from reviews I've seen. Also you can check GPU usage in the catalyst driver. It shows 1%... it should be way more cause I'm pretty sure UVD is on done on the GPU core itself (that's why the transistor count went up a lot from 2900 to 38x0).
 
Can someone else with a 38x0 test what their GPU or CPU usage is during H.264 or VC-1 playback?
 
What if you download a 1080p trailer from apple? Is that supposed to be played by UVD? When I play those I get like 3-5% GPU usage. I'm confused :confused: I wish ATI made their own Blu-ray player like they did with DVD in the old days..
