WDAM-7, digital 7.1 local outta Hattiesburg/Laurel, is the ONLY CHANNEL with audio the consistency of chopped liver, and video the texture of gravel....pixellated for days on end; LITERALLY, FOR A WEEK, SINCE the Kentucky Derby broadcast. Every other channel via Roku Express and a JVC Roku box, is beautifully pristine. Clue me! I contacted DAM-7 newsroom, and griped about not being able to view severe weather live cut-ins to keep track of local Tornado warnings. SOMEBODY needs to light a fire under these guys' rear-ends until this digital signal is cleaned up! I have restarted my entire Roku rig 3x this week!!!!
