PureVideo tec on GeForce 6 series

Any DXVA decoder can use the hardware decode assist of the Geforce6 but only the nVidia decoder gets access to the fancy deinterlacing etc. Since every half decent graphics card for the last 3-4 years has had hardware decode assist for MPEG2 that isn't really a big deal. The adaptive deinterlacing is however and that is what I was referring to.

 

I have never had to pay any extra to be able to play DVDs on my PC. I'm not sure where the problem is, every videocard sold today comes with DVD software for free. And pretty much every player i have, be it VLC, WMP, Realplayer, NeroMediaPlayer, and of course PowerDVD can play DVD. Never paid. Ok i paid for Nero, but that was a package.
Am i missing something?

 

Nearly all RETAIL cards come with bundled DVD software, most BULK cards do not.

 

Oh.

 

I can't get the nvdvd trial to play any dvds, says it can't find nvidia audio decoders?
Do I need to uninstall power dvd for this to work?

 

I had problems gettin the trial to work until I uninstalled an AC3 codec I had on my computer.

 

Most DVD players will allow you to choose the deinterlace method used and all of the good players have decoding engines that will properly use the video card's decoding features.

Ati's cards from Radeon and newer will also adjust the video strem to be in sync with your desktops refresh rate.

 

Ok got it to work.
What a lame player.. it's like media center style or something.
No mouse.
Cpu usage wasn't much better- 15-20%.
I am still baffled by my 8500 was able to do 5-10% cpu usage without a dvd decoder installed, just the DXDA working.

 

That isn't quite right. The driver provides basic DXVA acceleration for MPEG2 decode. They would fail WHQL if they didn't (I have also tested it personally).

What they don't provide is access to the features of the Geforce6 that are supposedly different from every other chip out there. Those are the accelerated motion estimation (for video encoding) and the fancy deinterlacing.

One interesting thing I noticed is that the hardware decode acceleration on the 6600GT gets disabled if you enable TV out (clone mode or full screen video on the TV). If it is driving more than one display (I haven't tried DVI) then the DXVA interface doesn't seem to be available.

The Radeon 9500 Pro I have can quite happily accelerate decode with two displays running (and is also faster at HD WMV playback).

 

Just how do you get WMV acceleration on your ATI video card? I thought the drivers for WMV acceleration were broken on the current video drivers. Even with the appropriate registry hack and enabling WMV acceleration on the ATI drivers, whenever I play back WMV HD clips, the CPU usage is at 100% and this is with a P4-2.8 CPU and 9600Pro video.

 

I have no idea if it is accelerating the decode of WMV. All I can say with certainty is that HD WMV plays with lower cpu usage and fewer (none) stalls on a Radeon 9500 Pro than on a Geforce 6600GT AGP in the tests I have conducted.

I have not done any registry hacks or anything like that to enable acceleration. The PC is a 3Ghz P4C with 1Gbyte of dual channel DDR.

 

Maybe i'm wrong here, but i did not expect some proprietary features of NV40 not to be available via DXVA.

 

Same here on GFFX, DXVA is only available in single display mode.

 

Damn PureVideo, I paid $670CDN for by 6800GT, and when I send an email asking why I have to pay more for this decoder, Nvidia gave me the corperate sugar-coated "f--k off"! Hopefully, ATI next-gen card will be more advanced then Nvidia's, so I can buy that.

 

Gosh, the audacity! Next thing you are telling me that Nvidia also make you pay extra to play games on the damn thing. God damn, what rip-off merchants!

 

Due to licensing issues, it is essentially impossible for nVidia to offer DVD software for free download. I was pretty sure, though, that most GeForce6 parts sold now shipped with a customized version of nVidia's DVD software. All of them ship with some kind of DVD software, though, and the difference between the different programs just isn't spectacular, so I don't see why anybody would care overmuch.

 

Can you explain? :?
I believed that if there was a feature advertised on the box, i don't have to pay another fee to exploit it... :?

 

I think what people are complaining about (what I am complaining about anyway) isn't that a DVD decoder app is required. That is standard practice for a number of reasons including licencing.

The issue is that the features listed on the box are only available with the nVidia decoder. No other decoder has access to the special features so you are forced to buy the nVidia decoder in order to access what you thought you had already paid for when you bought the card even if you already own a different DVD app. My 6600GT came with PowerDVD so I don't feel like paying for an additional decoder but I would like to have (and expected to have) better deinterlacing than the BOB and WEAVE that are currently available to me.

In addition to that the only front ends that I was able to use with the trial version of the nVidia decoder were Windows Media Player and the wierd Media Centre thing that came with it. Neither of these is anywhere near as easy to use as an app such as PowerDVD.
