</div>The problem is not cable quality, it's most likely common mode AC hum.<br>
<br>
Try re-orienting your cabling, especially if you are crossing AC power<br>
wiring.<br>
<br>
Make sure all of your gear is connected to the same AC power outlet (as<br>
much as possible).<br>
<br>
Make sure all your gear is grounded or, conversely, don't use grounds<br>
except for the protective grounds in the power wiring.<br>
<br>
A fairly good explanation of ground loops is here:<br>
<br>
<a href="http://en.wikipedia.org/wiki/Ground_loop_%28electricity%29" target="_blank">http://en.wikipedia.org/wiki/Ground_loop_(electricity)</a><br><br></blockquote><div><br>In my case, the HD-PVR sits directly beside the STB and the component cable goes directly from one to the other. The excess is coiled and bound with a twist tie. Everything is plugged into a single power strip which is plugged into a single outlet. Come to think of it, I actually have a second power strip plugged into the first (I know, I know). <br>
<br>I do have the monitor output from the HD-PVR connected directly to the TV. I can't imagine how that could be causing it but I'll mention it anyway.<br></div></div>
