Gefore 8400M GT card and Bluray not playing

I have a vaio vgx-tp25e/b HTPC. I upgraded from 32 bit Vista premium to 64 Bit Win 7 ultimate. I installed Nvidia driver version 190.40 from laptopvideo2go.com, and this is the latest driver for my card when I go a search on laptopvideo2go site using my graphics card hardware ID. The nvidia control panel says that my system is HDCP-capable but when I play bluray using powerdvd 9 (trial), the player displays this message:

"Playback stopped because your graphics card driver is incompatible."

I also have Windvd pro 2010 is crashing when I play bluray and it is an activated version. I can read the bluray disc from explorer so I don't think it is a bluray driver issue. Anyone else have had this problem and know the fix? I think it's with the HDCP requirement becuase when I run the cyberlink BD advisor it says that my graphics driver is NOT HDCP capable but NVIDIA control panels states the opposite. Thanks for the help in advance!

Hi,

I had the same problem with a NVIDIA ION Gpu. The problem occurs when the resolution is set to somethig more than 1600x900. The only thing that worked was to set the resolution to 1600x900 and the PowerDVD 9 playback started working. This is not ideal I know, since I would like to use higher resolutions. If you have other information regarding this, please update this thread.

Thanks!

I have a Sony Vaio VGC LT19U on which I did a clean install of W7 64 bit, but had the nVidia driver problem with the nVidia GeForce 8400M GT. I have looked high and low. Tried several modified nVidia drivers from laptops2go.com. Tried modifying inf files myself, used the nVidia Mobiiity Modder Tool. All allowed the display to work properly but I COULD NOT PLAY BLU-RAY disks! This worked! The Cyberlink PowerDVD still has a red mark next to the newly installed driver but it works so I don't care. I am having some issues burning DVDs in some video creation software (Ulead VideoStudio X2) but not sure yet whether that is problem with driver or the poorly documented and explained software package...

I have exactly the same HTPC as you. With exactly the same problem, no blu ray using Windows 7 Ultimate. And, by chance, I have tried the exact same programs (WinDVD and PowerDVD) that you have with exactly the same results. Question for you, did you try the suggestions in the previous two or three posts about installing different NVidia drivers, other than the one for Vista? I have tried 190.40 off of Download NVIDIA drivers | drivers for mobile cards and laptops | laptopvideo2go.com with the same results as the Vista driver that came preinstalled. I'm really at a loss with this one.

Sony, in their policy of corporate indifference, isn't going to be of any help for us since, "we don't support anything except the OEM system."

I think I might try the procedure outlined in one of the previous posts NVIDIA Driver - Convert from Desktop to Mobile (Laptop)

At this point, I'm not convinced the problem is solely a NVidia driver problem, but then what else could it be?

Hi All - I have a Sony FZ-480e/b and I'm using the 186.91 driver and everything is working. Including the blu-ray hdmi and also s-video out to an old 55" Toshiba rear projection tv. When you unpack that driver there is a folder that has a couple .inf files you need the whql file from that folder. It has our 8400m gt info. I am running win7 32 bit so i'm not sure about your 64 bit use. I tryed that 195.55 beta. It didn't install and luckily went back to the 186.91. The Windows adviser says that my gpu driver is not compatible with win7. I have know idea why it says that.

I hope this is some help to you

I'm glad your blu ray is working. What software are you using to play the disc? I'm using the exact same driver and no go. Since my computer can't run the 64 bit version, we probably have very similar hardware and if it works for you....well, that tells me I'm likely missing something.

Here's the solution to the problem for the benefit of westgstreet, the original poster.

The problem is the video driver. Use the one indicated at 186.91 WHQL at Microsoft Update (all desktop + notebook cards) - Guru3D.com Forums

It will not work initially because for some reason or other the actual driver file (*.SYS) will not get updated. Go into device manager and update it there, pointing to the directory where that driver was unpacked. It will take about 10 minutes to complete and look as if it has crashed, so give it time. Once the actual driver has been installed, this model will play Blu Rays.

And, thanks for all the thread participants who at the very least, pointed to the correct driver that Sony will NEVER place on their support site.

That's Great! dpetro - I am using Windvd 2010.
