AT&T U-verse → Re: Channel Pixelation problem - UV Realtime screen posted

Considering you've only had about 46 minutes of one line or the other being down for the past 5 months, I would say your line is stable. The best thing to do would be to have the ATT techs themselves evaluate that decision. It's always best to have the physical line tidied up rather than have to resort to a software bandaid.
If you don't have any HPNA errors or lost packets, and only specific channels are messing up, then the real problem is in the VRAD where the fiber terminates or in the video hub office where those feeds get sent to your entire region.

Thanks, I will try and document the times and channels and go from there. I appreciate your advise.
