There has been a very minor brrripp in the audio of ESPN HD channel 206 for a long time. Dating back to college football season. I have 2 SD (Standard Def) receivers in rooms that still have 2 SD TV's that are working just fine. But on my 2 rooms that have HD receivers there is that glitch on ESPN. Don't even try to be cute & tell me to "red button reset" my receivers or check my signal strength because it's already been done. There is a glitch and it has to be the ESPN HD feed. Can someone help get this channel fixed please?
