That is a possible fix, this is a transformer, You would want to keep the vcr/tv end of that as short as possible. The price is right. My question to this would be, if it is a common condition, why is this not an internal component of any tv, vcr, or sat system? Or why is this not supplied?, OK cost, but if it is an automatic improvement to products (isolation, less Hum, why is it not there? We have all kinds of sat systems here at work, cable, and DSS. Not once, on any installation has something like this been used. Because it is a transformer, and being RF, it might knock the signal down, or cause channel bleed, or introduce other problems, like RF noise. But worth a try.

Hmmm... Good question. In my frustration I just assumed that audio and cable companies were not dealing with the issue because they are evil :-) Better to let people think it's their fault (e.g., bad wiring) or spend $100 for a solution. But maybe there will often be drawbacks to an inexpensive solution (I'll let you know once I get the Xantech gadget).
On the other hand, my limited experience suggests that most people are willing to accept audio hum, if it's not too loud. When the cable guy came over to my place, not only did he not understand the problem, he also seemed to think it wasn't a big deal. He said something like, "so you're getting good sound out of the TV, right?" (where 'good sound' means inteligible sound). If most people don't care about hum, then there's little incentive to provide a solution -- except for those who care and WANT to pay $100 for it!
