Hi DanMck,
Thanks for taking the time to post about the issues you have been having with the picture on Viaplay.
Usually when there is an issue with a single channel - and no other issues - it's usually related to the channel itself. As a 'just in case' I've taken a look at things this end and can see all signal levels and tuners are good on your boxes.
As you have more than one, is this happening on all of them or just 1? If it's all then we'll likely need to feed this back to the teams but if only on one then we may need to dive a little deeper on this.
Please pop back and let us know so we can help further.
Thanks,
