Nvidia Has A new Decoder with hardware Excelleration Called The
PureVideo.

Bringing the High-Definition Home Theater Experience to Your PC
Today’s consumers demand a high-definition (HD) home theater experience on their PC. They want superb picture clarity, stutter-free playback and multiple display connectivity options. The best way to achieve this is with NVIDIA® PureVideo™ technology.

Watch videos on your desktop PC, notebook PC, or HDTV without the annoying artifacts and imperfections of traditional PC-based video solutions. NVIDIA PureVideo technology is the combination of a dedicated video processing core and software that delivers ultra-smooth, high-definition H.264, VC-1, WMV, and MPEG-2 movies with minimal CPU utilization and low power consumption. And the high-precision subpixel processing enables videos to be scaled to any size, so that even small videos look like they were recorded in high-resolution.

Pretty Impressive!

Then it's hardly "A" codec, I think it's a hardware decoder for the codecs you listed.

Here's a link to previous discussions here about the PureVideo decoder:

Notice that some of us are using PureVideo with non-NVidia graphics cards. Yeah it really is awesome.

Every so often (maybe 1 in 20 times) when I am playing back an HDV m2t file using Windows Media Player with the Purevideo decoder I get a spontaneous reboot. No warning, no blue screen, no opportunity to save my files, just a reboot like I hit the reset button. When my system finishes rebooting it asks me if I want to report the problem. I always do since I believe that the quantity of such notices affects the priority given to such problems. Anyway, just the other day I got a notice saying there was a fix for this and it took me to the following web site:

http://www.elecard.com/products/products-pc/consumer/144/mpeg-player

Does anyone know anything about Elecard Ltd software? Is there a relationship with NVidea and Purevideo or have they just kind of hijacked this process to sell their own decoder? Also, does anyone know if their software is any good? I'm tempted to try their software with the free trial period, but I'm kind of scared to do this without knowing more about them.

Elecard rings a bell. Have they been discussed here before?

yes... all ATI Radeon cards have had video acceleration for many formats since their initial release in the late 90's. They just don't advertise it like nvidia because, well, it's an old feature that they've had for years.

I play HD in an AMD XP 1800 with a radeon 9250 with no glitches at all, all the way up tp 1080i.

Well, having an earlier Radeon 9000 model, I recently ordered the ATI decoder online. I had to pay for it because it wasn't a free upgrade to owners from before a certain date. Anyway, I tried it out and it was nowhere near as good as Purevideo with my older ATI card. Not even close. I'm back to using Purevideo.

It's not a seperate decoder, it's built in to the hardware. I didn't install anything except the drivers for it to work (I use the omega drivers now). It worked with my old ATI 8500, my current AIW 9600 & the 9250 I just bought for a different comp.

if you're talking about the multimedia center (only other download I can see besides hydravision), that's seperate. it's video player does great deinterlacing (all versions) compared to the normal wmp & it help accelerate divx specific files but mc isn't needed for the decoder to work.

I just put it on one of my machines that has a Sony SDM-V72W hanging off of both the second VGA port and the composite out of my 6800GT-based video card. It's pretty cool to be able to switch between display+display mode and display+HDTV mode - all the way up to 1080i right off the box through composite connectors. Neato.

Side note - I didn't see an appreciable difference in CPU loading for VOB files running off of my video drive. about 20-25% with and without the decoder on my machine... Hmmm...

Second side note - seems that the Purevideo decoder is only working with WMP - contrary to the documentation (and even H.264 playback in WMP is only in Black and White - kinda cool but not desired). Double-hmmm...
