Hmm, MPEG-2 decoding seems to work for me in WMP10 (or in Zoomplayer custom mode) on 81.98 drivers, but it seems to do nothing for H264 or WMV HD . . .

WMV HD 1080p worked just fine for me with the officials. These betas are working too. You have the hotfix for MP10 installed right?
Well I have the 84.12 drivers installed now and it seems to be helping WMV HD a bit. Instead of CPU loads in the 60s and 70s, I'm getting loads of 40s and 50s.
OK, I don't get what this is supposed to be doing. This is with a 7800GT.
* The PureVideo control panel icon only appears when playing DVDs thru WMP, not for any other formats - WMV HD, AVI, MPEG - or application, like WinDVD 7 Platinum.
* The Properties panel for the audio doesn't allow me to select the center speaker box, so it says output will be 4.1.
* I thought that I was able to play Apple HD trailers thru WinDVD, but as noted above, they either have no sound or make a terrible noise and have no picture. QT7 Pro runs fine, but PureVideo doesn't affect that, does it.
Are updates needed from the 3rd-party outfits like Intervideo to get this all working together? And WTF isn't the X-Fi supported?!?

For support, you need a 6or7 series GPU that supports H.264 acceleration, all but nv40/45, drivers with support, and you need to buy a supporting decoder from
CyberLink PowerDVD? with H.264 (AVC) and AAC Pack
InterVideo® WinDVD®
Nero® ShowTime

I'm still around. And obviously so are nVidiots such as yourself.
Oh, and BTW, the NV40/45 WMV9 decode acceleration is still broken.
edit - And you can now add H.264 decode acceleration to the list of non-functional "features" as well. Check for yourself.

Thanks for the info (and backup) DAPUNISHER.
If their codec outputs standard PCM to the audio device (pretty sure it does) I don't see how the X-Fi isn't supported. Anyhow, don't expect much with these drivers. It definitely won't work with anything other than what's listed on NVIDIA's page. It already doesn't work with Nero ShowTime for two of us either.
Nero 7 Update/ShowTime
Version Number: 2.1.0.10
Release Date: October 31, 2005
New features
Improved H.264/AVC decoder with 20-30% speed gain on Hyper-Threading, Dual-Core and multiple CPU systems
You need at least that version I'm guessing, but I'm going to give the latest (2.1.0.15) a shot.

As you can see, CPU usage was much decreased when enabling hardware acceleration in the latest version of Nero ShowTime. In fact, without hardware acceleration, the video simply couldn't continue whatsoever at one point. Playback with hardware acceleration on was butter smooth.

<Quagmire>Allllright!
Could you try it with your core speed around 300-50 and then 500 or higher? That'll shake out if the acceleration being tied to core clock is as important as suggested.
Since I didn't mention it earlier, I'm using da_vinci_code-tsr2_h1080p.mov (The Da Vinci Code Teaser 1080p) (150 seconds in duration).
This time I downclocked my eVGA 7800GT from stock 445/535 MHz (445/1070 MHz effective) to 300/535 MHz (300/1070 MHz effective) and 445/360 MHz (445/720 MHz effective).
H.264 - No Hardware Acceleration
H.264 - Hardware Acceleration - Stock Clocks (445/535)
H.264 - Hardware Acceleration - Lower Core (300/535)
H.264 - Hardware Acceleration - Lower Memory (445/360)
It looks like lowering the core speed actually did something. The memory speed didn't matter. That was the opposite of what I would have thought. Interesting.

I played a couple hrs with no readily detectable issues. Also, Any IQ difference, if present, would require closer scrutiny than I am willing to devote.
Thanks for confirming core clock has an impact on acceleration xtknight :beer:
Not sure of it actually, it's within margin of error. This movie is so big that it has to be paged a lot, or something. Results didn't seem consistent.

Percentage is 1 thing, but the way it stayed@100%@300 on the graph for a period, repeatedly, instead of just spiking as it did@445 seems to be another.

Perfect, no. But I do expect them to be relatively stable. After all. we're talking beta, not alpha. Q is right in this.
Got a BSOD from nv4_mini.sys with 84.12 drivers (I got lots from previous 80 drivers too). I did memtest86 today for an hour and no errors in all 2048MB of RAM. These 80 series drivers are quite unstable for me (whether the official WHQL, official beta, or non-official beta). It happened just when Quake 3 was about to come up.
BugCheck 100000D1, {baf8f020, 2, 1, b99b3e68}
Probably caused by : nv4_mini.sys ( nv4_mini+7ae68 )
DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If anyone else gets BSODs from these see if you get the same error as me? Or send minidump and I'll analyze and find out.

I got some freezes while playing FarCry earlier, but after a minute or so it kept running as if nothing ever happened. Then a little while later, I don't know what happened, but the game started acting crazy, video freezing every few seconds (only if I moved the mouse) but audio playing with no problems at all...it's been a while since I've played FarCry, so I can't say for sure whether it's these new drivers or not (I was using 81.98 before). I was also encoding video (h.264) in the background on Core 0 with FarCry on Core 1 (now that I have 2GB of RAM I can actually do that 
), but that shouldn't cause these kinds of problems.... (Edit: Plus the game and the video stuff were working from completely separate hard drives anyway)
), but that shouldn't cause these kinds of problems.... (Edit: Plus the game and the video stuff were working from completely separate hard drives anyway)I got the decoder installed on my 7800Go 1920x1200LCD. For DVDs in WMP10 you get the decoder options in the taskbar. The deinterlacing its really awesome. No change in divx, .264, or hd wmv.
hmmm let me update nero and do some tests. Since my 7800 is 250MHz default and i o/c it to 370, we'll see how it helps ( i can get over 60% boost in games ocing)

Dailytech has it as the latest top news story and a link to a preview. Looks like it has significantly lower CPU utilization compared to ATI in their testing. However, I think something is borked with their testing, the X1300pro shouldn't be capable of the same acceleration as the X1800XL for 1080p.
Tuan reported a playback issue on his Dell 3007WFP, but says the new betas fixed it. This is looking good for nV and H.264 acceleration, but IMHO, the continued listing of the requirements everywhere as needing a supporting decoder and 6/7 series card without mention of the nv40/45 lacking the capability is bad juju. If users fail to check that product comparison page and see their card isn't checkmarked, they could end up purchasing a supporting player with decoder only to discover it was wasted money :thumbsdown:
Even that preview states "This new version is compatible with the whole of the range GeForce 6 & 7" Am I the only one who checked that PureVideo produvct comparison page??? I have not seen any site mention it.

Yeah the MPEG2 stuff is quite good, now imagine that ATI AVIVO looks even better yet! H.264 is a going to be a BFD though, so I am stoked my cards are going to offer good acceleration of the 1080p content.
How do I make the purevideo decoder work with WinDVD7? I'm using an 6150 board and have 84.20 drivers. I have the option "use hardware decode acceleration" checked in WinDVD7.
I'm hoping to not have to use WMP if possible.
