I got a Nvidia Geforce 330 M GT on a Sony VAIO VPCCW2S1E, running Win7 x64 Home Premium.
when I watch videos on my notebook, I see weird, transparent, flickering lines. they're horizontal and perhaps a little bit skewed (it's very hard to see, and they only appear for a very brief time)
This issue appears when the camera in videos is moving somewhat fast. When the camera is standing still again, the lines will disappear.
The lines always appear in the same area, in the top of my screen, about 10% screen size below the edge of my screen (when I watch in full-screen mode).
it happens with all video playback software, windows media player, vlc, media player classic, etc.
I also tried different drivers, 29x, 28x 26x, but it happens in all of them. Of course I used "clean install" for the drivers.
in VLC I tried to disable the following options, which are enabled by default:
Accelerated video output (Overlay).Used hardware YUV->RGB conversions.Window decorations
... didnt help
But there was one thing that helped: setting the Video Output to "DirectX (Direct Draw) Output".
If I do this, VLC will disable Windows Aero, but the Video Playback will be fine - no annoying lines.
any other output mode however will have that line issue, or is not suitable for serious video playback.
Nevertheless, I'm still trying to find a better solution. Changing to Aero Theme all the time is very annoying.
Today I downloaded the official Driver for My Laptop, which is a damn old 188.67 driver.
Everything is ok with that official sony vaio driver, but since I play a lot of video games, I want to use the latest Nvidia Drivers and watch videos at best quality, without noise.
Can you please help me to fix the problem?
many thanks in advance
