Nvidia's PurevideoHD available for Sony's Go 7400 graphics card??

[Schmendrick1]

Hi,

does anybody know if the PurevideoHD technology is usable for Sony
Vaio VGN-SZ-3HP/B notebook which is equipped with the nVidia Go 7400 chip.
On the following nVidia-web page it is listed that the nVidia Geforce Go 7400
chip is supporting most of the high definition content acceleration.

Is a driver update require to use nvidia's purevideo technology?
Are the most recent nVidia drivers usable with this chip?
On nVidia's web site and on Sony's web site I have not found
anything more about this matter.

Any help is appreciated!

Hi Schmendrick1 and welcome to Club Vaio.

All the nVidia Go 7xxx Series support PurevideoHD.

As far as I can tell there is a free trial version for the Pure HD decoder but it is esigned for XP media center not Vista home Prem. I'll set a restore point and try it out on the HD Projector. My fear is it isn't a Sony endorsed driver set and will BSOD

Thanks @Blencogo and TonyBeard for the response!

I am using XP Professional SP2 and I wonder if I would
require to install new graphics card drivers newer
than Forceware-Version 84.91 which is currently installed
on my system and where I can obtain/purchase a PurevideoHD-
decoder software/player utilizing this hardware acceleration
technology? Is this included in PowerDVD 7 Ultra-Edition
or WinDVD 8 Platinum or is there any other decoder/player
software taking advantage of this.

A few months back I read in a forum that only the latest Japanese WinDVD 8 version was producing true HD and you can download it from their website. It has probably been released to more countries by now. Anyway I'm still testing Nvidias trial version of PurevideoHD on my Ar31s using vista.
I can report that whilst booting has become slower and it has taken a bit of time to settle in after a defrag, it distinctly improves avi, dvd and even freeview TV pictures remarkably. I would say depending on the original (filmed in HD or analogue) it has reduced stutter and improved image by about 20%. The blu ray WinDVD stutters less (after pausing) but I can't detect any noticable improvement on a razor sharp image but colour does seem more vibrant. By the way...I don't recommend pausing a blu ray movie...it caused an annoying stutter that is intermittent but was fixed with a couple for defrags with Perfect disk 8.
