For what it's worth:
I have noticed this for a couple of weeks now but thought it was my imagination.
Earlier tonight I was watching Sons of Anarchy on my iPad Mini at the gym, then came home and watched it on the Apple TV, and was convinced it was not my imagination. Found this thread.
50 down 10 up from Comcast. Hardwired to the Apple TV.
Checked software update and somehow I was still on 6.0.1., so I don't think it is related to the 6.0.2 upgrade.
Big shout out to Vandergraf for the tip about that example video -- I did not know that existed. Tried it on the Apple TV never got above 1000.
Tried it on my other devices that do Netflix (TiVo, Roku) and I'm in the 3000's. Even my iPhone did something in the 2000's.
Thanks all please update if you learn more.
