Stuttering and pixalating

[Kenoman]

Anyone have problems with stuttering and pixalating? When watching a show all of a sudden it will freeze for a second then continue. This is very annoying. It happens more on the channels above 1100.
Don't know if it's the station or my SA8300HDC boxes. Yes, it happens on both boxes I have.

Could be a couple of issues... could be signal strength (ironically, either too low or too high)... or it could be a problem with the box. Your best bet is to contact TWC and have them check signal strength, and if that looks OK, try swapping out the box if you have the opportunity.

We had that on our SA-8300HDC box for months.  Tech came out and replaced the line.  Everything was fine for awhile but than would come back within days to hours of a box reboot.  

The second tech noted a corroded cable in the back of the DVR that was causing all of our problems, he replaced that, and the problem has not only ceased, it has not come back for almost three months.  It could be a signal, line issue, or a box issue as well, but I would ask the tech to please check the cables in the back of the TV/DVR as well as the lines.  We were so sure the box was going bad, and in our case, it wasn't the box at all.
