I mentioned this in another thread but it got buried and thought I'd bring it up in a separate thread. I have a Comcast subscription that allows me to stream live content via an app on my iOS devices. Works great - until I try to use Airplay and send it to my ATV. Spits, sputters, never plays more than 1-2 seconds before quitting. Totally and completely unwatchable. I can stream XFinity from my mid-2013 MBA via the Xfinity website - no problem at all. Hulu and Netflix stream perfectly from all of our iOS devices. Only XFinity is problematic. Do you suppose it could be the XFinity app causing the issue? If not, what then? ATV is gen3 with latest update, I've tried wired and wireless connection to the ATV - same issue.
