Videotron 8300HD Diagnostic Screen
anyone know how to get to the diagnostic screen in the 8300HD? I saw the installer do it when he brought the device in to test the line quality and I'd like to be able to do that myself. The reason why you ask? I've noticed the occasional screen stutter and artificating that I've never seen before when watching TV. I'm wonder if its related to a cable split I've made and I figured this would help me figure it out.
