Hi @YvesGuy,
Thanks for your post.
We're here to help. Have you tried streaming other tv shows or movies and seeing if there's any difference? Have you tried attempting to resolve the issue by uninstalling and subsequently reinstalling the impacted channel? Prior to adding the channel once again, it is advisable to restart your TV in order to ensure a successful outcome.
Let us know how it goes.
Regards,
Nimfa
