Has anyone else's cable been skipping? Where the picture freezes and gets pixelated? This happens in pretty much every show on every channel. Some channels are worse than others.The audio freezes as well. When we called Comcast, we were told it was a neighborhood problem. And that they were working to fix it. But that was 10 days ago, and we are still having the issue. We are calling back today. But just wondering if anyone is having this same problem. Thanks!
