Juddering on Discovery+ UHD feed

[DrewShire]

Got Stream delivered yesterday and set it up. Now watching live football on TNT Sports through the Discovery+ app. On the UHD feed, there's non-stop shuddering, the footballers slow down then speed up as if on fast forward, the ball blurs on long crosses etc. Have turned on the 'app judder' setting in the Stream settings. Have tried wireless and ethernet connection and nothing's helping. HD feed is better but still not 100% smooth.  It's as if the Stream box can't cope with the UHD feed in particular. Have 500 meg broadband so connection is not the issue. This does not happen when watching on the native app on my Samsung TV so going to have to watch it there as the Stream app is pretty unwatchable. 

Any ideas on how to impropve this please?

I think its got worse recently and am also watching the footie via the native Samsung app as the juddering on TNT makes it unwatchble. 

I suspect the puck is unable to cope with the UHD feed.

Naaa it's the Discovery+ app because they're moaning about it on the BT forums as well. It doesn't appear to be handling live events very well
