Watching U-verse TV

Two to three times per week, the U-verse picture gets badly pixelated exactly at 6:30 PM EST on all channels and lasts for about 20 to 25 minutes. I have tried to research but can't find a solution. The picture gets frozen in the pixelated squares and it progresses very slowly, but doesn't have any

Understand that ATT does not want to support Uverse going forward. Is Direct TV any better or should I find a new provider?

My U-Verse account has rebooted six times today. Is this unusual or what I should expect going forward?
