I would like to confirm you have the latest graphics drivers installed. Check if you have this version 22.214.171.12461

Allan: Thank you for trying to help me. I have version 126.96.36.19961 installed, but the flicker during Netflix playback still occurs. What next?
You mentioned that issue started occurring a couple of weeks ago. Prior to that I assume it worked OK? Did you make and changes to the system or updates just before the issue began? Did you install any new applications or programs prior to the issue occurring? Hardware changes? Do you by any chance have another system that you could connect to Netflix with and verify the issue?
In the past, yes, it worked for a short time as far as I know. The first time I saw this issue was really the first time I tried running content on Netflix that wasn't a cartoon for my daughter. And for those, I let her watch while eating breakfast as I got ready in the mornings so I wasn't paying close attention. In other words, it could have been occurring the entire time. I'm really not sure.
That said, the only change I think I've made in the last 2 weeks has been to add a Netgear WNDR3700 router to my network that I use to handle the internet in place of my (now bridged) Uverse Residential Gateway. Checking Netflix on my other desktop, Xbox360, and laptops...no issues. Just this computer.
Are all the systems connected via the WNDR3700?
Yes. As of today (issue still occurs after I made the change in connection today), all systems are connected via LAN through the WNDR3700.
