Streaming video from iMac fails to AppleTv 4k
Hi, recently I've noticed streaming HD video from my TV library stored on my iMac fails onto my 4K apple tv. Not 100% but this seems to align with Big Sur & TvOS update as not really attempted it for a while.
It'll start to play and then maybe 60 seconds later it'll pause and never recover. The menus are sluggish at the same time.
The 4k box has a wired network connection as does the iMac
Streaming the same content to my old HD box (wifi) works perfectly.
Any ideas?
thanks
Apple TV 4K, tvOS 14
