Hi Nick. Thank you for posting this information. I have forwarded your letter on to the executive office representative for Altice that is handling my FCC complaint on this issue.
I did hear back from him this morning.. A couple of things -- first, Altice has classified this now as a "outage", and assigned it an outage number. They classified it as an outage on 9/22. That means it has also been forwarded to their engineering group.
The second thing I wanted to note.. Over the weekend, I did pick up 2 of their Samsung boxes for our most-watched televisions in the house. I will say -- this issue does seem to impact those boxes as well, BUT - they recover much faster from it. You will get a very brief moment of pixelation, and its usually only visible in small sections of the overall screen. If you're not looking for it, you'll likely not even notice it happening. This seems to match up with what other Optimum users had reported that were using Cisco/SA CableCards - that they either did not have the issue, or their posted examples of it were so slight that it wasn't disruptive. Their Samsung boxes are using tru2way, and do not have CableCards installed.
It does seem that the NDS cards choke on this more severely.
