That's what I thought. Tried changing from Google DNS to Time Warner's DNS and it had no impact on my situation.
As a sidenote, I upgraded my Time Warner internet service from "Ultimate" to "Extreme". With 50 down and 5 up, I'm still having problems getting Netflix to stay in HD on the ATV. Sometimes it will stay for quite a while and then just drop into unwatchable blurriness. Other times, not a chance.
My current status -
I have an ATV3 wired and an ATV2 wireless. Both are on 6.0.2. Symptoms are exactly the same for both.
The Netflix example short typically starts off high, sometimes as high as 3000. Then it drops to 235 or 700. Occasionally it will jump back up. I have not seen it higher than 3000 after the infamous November 11 date. Prior to then, I had flawless Netflix access on ATV since early 2012.
My Playstation 3 is wired. When I run the Netflix example short on that, it will start out low and then ramp up to 5800. It stays there and does not move. For now, I am watching all Netflix movies and shows on the PS3 instead of the Apple TV. Let's hope Apple and/or Netflix sorts this out.
