Okay, here's my problem. 

 

I've got an Apple TV (Model A1469) and a PC with Windows 7 Professional 64-bit running iTunes for Windows 64-bit (latest version).  I'm using the PC to act as a server for all iTunes purchases.  I've got an Airport Extreme Base Station (Model A1034/M8799LL/A), a 16 port switch (Netgear) and Cat 5e as my wiring.  I've got both the PC and Apple TV hard-wired on my LAN. 

 

So far, movies and TV shows in HD only (720p or 1080p) are taking forever to stream from the PC to the Apple TV; SD content is fine.  If I stream the same content in the cloud via Apple's iTunes servers to the Apple TV, it is pretty quick all the time.  The problem only happens when streaming from the PC to the Apple TV using my wired LAN.  I've tried changing the settings in both the Apple TV and iTunes to better the performance, with no luck. 

 

Is the problem in the Cat 5e or is it something else, like iTunes for Windows?  I'm at a loss.  Am I missing something?

 

Your answers are greatly appreciated.

    Hi Joe,

     

    It sounds like there is an issue buffering or loading the videos on your Apple TV when using Home Sharing. The suggestions in the articles below will help make sure your network configuration is compatible.

    Resolve network or streaming issues

    If you're streaming content from a computer or iOS device using Airplay or Home Sharing, try these steps:

     

    Troubleshooting Home Sharing

    4. Check your network connection

    Home Sharing requires a home network with an active Internet connection. All the devices you want to use with Home Sharing need to be connected to your home network.

    In addition, verify that:

    • All your devices are connected to the same router, if you have multiple routers. Using multiple routers may prevent discovery between these devices.
    • Your devices are not using a Virtual Private Network (VPN), or that they are all on the same VPN. A VPN may isolate the device and cause connectivity disruptions.
    • If you have a router set up with a guest network, make sure all devices are either connected to the guest network and devices on the guest network are allowed to communicate with each other, or switch all devices to the primary network on your router.
    • If your computer is asleep or shutdown, or iTunes is closed, there's no access to the shared iTunes library. Wake up or start the computer and open iTunes to regain access to that library.
    • Your router needs to be up-to-date. If you are using an AirPort or Time Capsule, learn about firmware updates. If you are using a router from another manufacturer, contact the manufacturer to inquire about available updates.

     

    5. Check Firewall settings


    If you have a firewall enabled in your router or computer, make sure that the firewall is not blocking communication between your computers. Home Sharing uses TCP port 3689 and UDP port 5353 to communicate with shared iTunes libraries.In addition, Apple TV and Mac computers will use port 123 to set the time automatically. Incorrect date and time on either the computer or Apple TV can cause errors for Home Sharing and connections in general.If you are unsure whether your router has a firewall or the required ports open, test additional devices or another network to help isolate the issue. If the devices tested work on another home network, it is your router or network configuration.For Mac OS X, you don't have to edit the port addresses, but make sure the firewall in Apple () menu > System Preferences > Security > Firewall are not set to:

    • Block all incoming connections
    • Allow only essential services

    If you use another security/firewall software on your computer or router, follow this article or contact the manufacturer or check the documentation on how to open TCP ports 123 and 3689 as well as UDP ports 123 and 5353.

    For more information on ports used by Apple products, see Well known TCP and UDP ports used by Apple software products.
