Only audio AirPlays to Apple TV

Hi all, I know I don’t need to do it, but I can’t get audio and video to AirPlay to my Apple TV. Only audio comes through. I have a 4th gen Tablo. (I know I can just use the Apple TV app, but I’m wondering why Airplay doesn’t work with Tablo. All other apps Airplay just fine.). Thank you!

Does apple air play support mpeg2. Apple in general doesn’t like mpeg2. Maybe the FAST channels work since they are usually H.264

Sorry, what are the FAST channels?

Free Ad-Supported Television. These are the internet-delivered channels that are included with the Tablo.

Ah, thanks.

Nope. It does not…

But try the free FAST channels and then try playing a recording of video.

Tablo stores the OTA as received but does post processing for thumbnails and the result should be H.264 format.
