Hey there cahardinge,

It sounds like your are experiencing playback issues with when Airplaying content through your receiver. I would recommend these steps for you from the following article, named:

Troubleshooting performance issues with AirPlay or AirPlay Mirroring

If you are experiencing intermittent playback or significant network lag with AirPlay or AirPlay Mirroring, it could be due to a weak Wi-Fi connection, interference, or the distance between the Wi-Fi router and your iOS device, Apple TV or AirPort Express.

Try the following suggestions:

• Ensure that other devices are not trying to stream to the same Apple TV at the same time.
• Ensure that your Wi-Fi router is set up with the recommended settings for the best performance.
• Certain external devices, such as microwave ovens and baby monitors, may interfere with a Wi-Fi network. Try moving or disabling these devices.
• If possible, try to locate your Wi-Fi router in the same room as your iOS device and Apple TV.
• If your wireless and wired networks are the same, try connecting your Apple TV to the router via Ethernet instead of Wi-Fi.
• If the Wi-Fi router has an external antenna, check to see that is it connected properly and in good condition.
• Use the Wi-Fi network troubleshooting guide to resolve interference and other issues.

Thank you for using Apple Support Communities.

All the very best,
