On Demand Stutter/Pixelation
I have a Contour box and my Cox modem/router plugged into a splitter, which is then plugged in to the wall connector. When I try and play On Demand content, I get video and audio stutter/pixelation to the point where it's unwatchable. I also get this effect occasionally on live channel viewing, but not enough to annoy. I reached out to Cox last week and the rep I spoke with recommended I replace the splitter, which I did, but the problem remains. However, when I connect the Contour box directly to the wall connector, the problem is eliminated immediately. Also of interest is that when I connect the Contour box to the splitter, but remove the connection from the splitter to the modem, the problem disappears. The Cox rep I spoke with last week said that a tech can come out, but that it could cost me $75. This doesn't seem right considering I'm limited in my options, and have already attempted two out-of-pocket purchases to remedy the situation.
What can be done to fix this, without having to shell out any more money to additional equipment or a tech visit?
It should be noted that both splitters were brand new, and both rated very highly online.
Thanks to whoever can assist.
