Slow streaming Apple TV

Just wanted to throw my two cents in here as well.

I've recently been experiencing the exact same problem as all of you.

This is my setup.

15" Retina MacBook Pro running OS X 10.9.2

I stream personal content wirelessly using a dual-band router connected to my wireless-N network.

This streams from my MacBook Pro to an Apple TV 3 with the latest update using iTunes 11.1.5.

I have a 50+mbps connection so no issues there.

Netflix streams beautifully at its highest quality. YouTube videos load in seconds and play without a hiccup.

Apple Trailers are abysmal and I have given up on those a long time ago, but now, my personal videos won't stream at all unless they're limited to around 800mb or less. Anything over a gig will barely buffer, then choke and rebuffer until I swear and shut the whole thing down.

This "used" to work flawlessly, but sometime in the last month it's all gone down the toilet.

You need to revert back to iTunes 11.0.4.4, and you will be able to play your videos.

This is the same exact thing I'm experiencing. It seems like these forums keep sweeping this issue under the rug.

Just keeping the thread alive. I tried to rent a movie from iTunes and it kept choking. Bandwidth is 30Mb/s +. However, streaming from YouTube and Netflix seems a little slow. I'm having to stream those from my TiVo to get decent video quality.

I've about had it with Apple. Roku is looking mighty good about now.

Internet speed is only one aspect, assuming you verified it via speedtest

Check that DNS is set to auto, if on wifi try Ethernet. Get a network report from istumbler, netstumbler or similar.
