I called PBS 8 several months ago and asked them about the blurps problem with the audio. They said that they knew about it. Here it is several months later and it is still there. It is unwatchable. Looks like I won't be watching Ken Burns Parks series. I still get it a little on the other locals but not near as bad as PBS 8.
I sent them an email a few months ago complaining about the burps and pixelization problems. I did receive a reply stating basically that they were working on it. Of course it's never been solved, so I wrote them another email about three weeks ago. No reply this time. Maybe I insulted them by suggesting that since the other locals seem to have solved most of their problems, why don't they ask for help!
