I have been having issues over the past few months with a single HD channel (ESPN) where the audio and video feed stutter and have visual artifacts. I have attached two videos since the issue is difficult to describe. I have no issues watching the channel in SD or with other channels, only HD ESPN. I have reset the STB multiple times, done the self-diagnosis, and reseated the coaxial and HDMI connectors to no success. Any input would be greatly appreciated!
which self diag did you do?
Tune to 570
Menu>customer support>system Information and then press info button.
left side will show SRN for channel.
You can move the box to a room that 570 works fine. If issue follows box it will need replaced.
You can also try reseating cox at splitter or replacing splitter.
