Netflix - screen tearing problem

[DiffikultD]

I'm not sure exactly when this started, but it's been a few months, at least.

 

While streaming video on Netflix, I get a screen tear right in the middle of the frame. It's constant, anytime there's action or whenever the scene pans. This occurs in Firefox and Chrome, both latest versions. Silverlight is also latest version. Otherwise, the video quality is perfect. Plays in HD, no stuttering, no choppiness, etc. All other video content and players (Youtube, Flash, DVD, VLC, etc) work fine.

 

In the Silverlight settings, the option to enable hardware acceleration is greyed out. I suspect this is because I'm still running WinXP, but I'm not sure. This only started in the past few months; I had no issues for the first two years running Netflix. I've even tried playing around with the VSync settings in nVidia control panel, to no avail.

 

Any help would greatly appreciated. Google shows a lot of results, but so far, no solutions.

What graphics card drivers are you using?
Did you update the drivers just before you started having the issues?

You can try updating to the latest version if you dont have it yet, or you can revert to an older driver from before you had issues.

Wow, that was quick.

Intel Pentium D 820 2.8 GHz
EVGA GT630 2GB [edit: driver 320.49]
4GB RAM

WinXP SP3

I don't believe I updated the GPU driver around the time this started happening, and I haven't updated it since. I'm pretty sure I'm maxed out on this ancient PC.

Are you using a TV as a monitor? More specifically, are you using a TV as a second monitor?

No. I have 2 PC monitors, both at 1680x1050. 60hz refresh.

Are you watching Netflix on the second monitor?

Are you watching Netflix on the second monitor?

I've tried every combination I can think of. One monitor at a time, both monitors in Dual View with Netflix on one, then the other. It behaves exactly the same. I can't use Span mode because one connection is DVI, the other is HDMI. (I used to be able to run in span mode when I had two DVI connections, but I replaced one that only had HDMI and VGA connections. Yes, the screen tearing started before I replaced the 2nd monitor.)
