Hi guys -- I'm not sure if this is the right forum. I have a Vaio Z-590 notebook with an Nvidia 9300 video card (it's a hybrid solution so it's difficult to use non-Sony drivers).
I am using the official Sony 32-bit Windows 7 drivers (Forceware 186.84). However, I am having problems with deinterlacing and my notebook fails the "jaggies" test in HQV. I've tried all the settings in the Nvidia Control panel, WinDVD, PowerDVD, and even the SD & Blu-ray versions. I tried in Vista with the official Vista drivers and I had the same issues. Does anybody know of a solution??
I did find this online:
"Nvidia Drivers: Blu-ray IQ Enhancements Have Been Broken Since 182.5
This was a surprise. When we contacted Nvidia to confirm our image-quality results after our tests were completed, representatives there told us we weren't seeing what we should. Further investigation revealed that drivers newer than 182.5 have a bug that doesn't allow for jaggy reduction (diagonal filtering) in the GeForce 9300/9400 and turns off film-mode detection in the GeForce 8200.
After we learned about the bug, we re-tested with the 182.5 drivers and "voila," the image quality improved. We therefore tested the Nvidia chipsets using the 182.5 drivers, and now that Nvidia is aware of the problem, it is working on a solution for future driver releases. All will be well soon enough.
A final complaint about the Nvidia drivers: noise reduction still doesn't seem to be enabled by default. I assume this is because slower systems might take a notable performance hit with this feature enabled, but it would be nice if the driver would detect the CPU and automatically enable the feature if there was enough horsepower to handle it.
Update: Since this article was written, Nvidia has released a new 190.62 driver. We haven't had time to test it to see if this bug has been fixed, but Nvidia doesn't seem to have mentioned it as a resolved issue in the driver release notes."
