Device to stop ground loop hum from CATV in my HT?

Hi guys.
I am having problems with what I think is CATV ground loop hum in the audio section of my high end home theater system. I say "I think" because it started as soon as I introduced CATV to my system through the VCR, and because I have taken enormous strides (and lots of $$$) to keep my system quiet (all components on one dedicated circuit, hospital grade outlet, power conditioners, RCA Caps, et al.)
I have seen a couple of gizmos on the net that claim to eliminate a CATV ground loop. Both of them consist of a small device with in and out F-type connectors, that attaches to the COAX before it feeds into the VCR. One is called the ISO-MAX (see http://shop.polkaudio.com/customer/product.php?productid=38&cat=6) and the other is the Tributaries Ground Guard.
Does anyone have experience with either of these units? Do they work? Do they significantly degrade the video or audio CATV signal? Is there another device that is better? Price is not really an object at this point, as I have invested quite a bit in the system already. Any help would be appreciated.
Thanks,
Rob
