Your friendly CEDIA Installer here. Just get a ground loop isolator. Audio ones are pretty cheap and can be had at Radio Shack. Video ground loop isolators are a little more expensive. In my experience, the most common cause is a difference in voltage potential between two pieces of equipment in the same setup. Most commonly is people who have their computer hooked up to their stereo and their stereo feeding the TV (video switching).

As like most things in life you can spend an arm and a leg for an isolator, but chances are the cheapo radio shack ones http://www.radioshack.com/product/index.jsp?productId=2062214 will get the job done.

Sweet podcast. Recently I listened to another "1st podcast" and it was painful to listen to. You guys are like pros already.

I'd put in a request for less compression. Perhaps it's the Skype. Seems like the compression sounds are on both voices.

Your local CEDIA installer here again. Just wanted to say that we field terminate all our component cables when doing a custom install. We actually use a system that provides us with a single compression fitting (since time is literally money), but the concept here is the same. Don't buy your cables at the big box store. Make 'em yourself.

As for monster. We sell them at retail. Our retail markup is around 100%. If our markup is 100% and we get them from a distributor, just imagine what they must really cost monster.

As far as I can tell the 12.8 Mb/s figure only refers to the audio transmission rate. If you look at their "Digital Audio Extender" product, it has the same 12.8 Mb/s spec. Their other DVI over Cat-5 product (DVI CAT-5 Extender) spec list says: "Video Amplifier Bandwidth: 1.65 GHz". Presumably this new product is a combination of the other two products and so the figure isn't representative of the video bandwidth.

802.11g WiFi is not nearly as "bulletproof" as a hardwired system is. Microwaves, cordless phones, your neighbor's 802.11b device: they all have the potential to interfere with a 802.11g signal. This devices uses 2 Cat-5 cables. All 8 wires in both cables. Regarding source devices being far away, you need to think about the high-end custom market where an entire house's equipment is in a rack and all the outputs are pumped throughout the house. LCD TVs in far off places. Even if you had a projector in a theater room and the room was a bit too far from your source gear, you'd need a DVI Extender. I'm a CEDIA Certified Installer and a Gefen dealer and this device along with other Gefen products are a huge help in multi-room AV systems.
