Playback Failed (device disk full)

I seem to be getting the above error message when playing live tv off my hd homerun for most channels lately. When I play on the had homerun app, it’s mostly fine if a little studdery, so assuming there’s a weak signal at play maybe. But if that’s the case wouldn’t I get the weak signal message? What’s the device disk full message supposed to indicate?

I should note I have plenty of storage left on the channels server machine.

How much space do you have on the Client ?

Oh you know what, it’s my Apple TV and it’s only 32GB. It doesn’t tell you how much free storage is left on Apple TV but I deleted a bunch of stuff and so far so good.

We will try to raise this issue again at WWDC this year, but so far in the past we haven’t gotten any helpful response from Apple on how to work around these issues with the AppleTV sometimes not clearing its cache automatically the way it is supposed to.
