The person that wrote this to you is incorrect. I emailed our contact at Filmon and told them about this email you received. This is their response to me....
I've copied the techs who are most familiar with the ongoing PUNCH TV pixelation problem and have alerted those who oversee the email@example.com team with the latest info.
Just so you know, I never told the support team that the source signal was the problem, and I'm not sure where that response came from. What we have talked about internally is that we are still not sure where the problem is coming from. We are not experiencing a problem like this with on other channels, so we are mystified, but we are still looking to troubleshoot the problem.
We are delivering a clean signal and they are working on the issue on their end.
