Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Recently purchased a new Roku Ultra, but unfortunately certain shows on Netflix have very choppy playback. I'm still working through which shows exactly this happens with but right now it appears to be focused on shows from European origin such as Great British Bake Off, Lupin, etc..., Other shows don't have this issue, nor do other channels (HBO, disney, etc...,) and I've reset, checked for updates, and done all I can think of to resolve this issue but nothing works.
I should note that my old roku worked fine and we never noticed this issue (I think Roku 3)
Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.
Does this clear up the issue you are seeing? Please keep us posted what you find out.
If this issue is only occurring on that specific channel, it's probably an indication that there is an issue with the channel itself and the channel provider may need to investigate further. Many channels on Roku are developed and maintained by the channel provider themselves.
