ERS Cloth uses

I thought surely there would be applications inside DVD/CD players; especially since the video and display being turned off are such a benefit to CD sound on a Toshiba SD9200 for example. The improvement must be due to reduced noise and 'if' that ERS does what they claim(and obviously some manufactuers have bought in)there must be uses in that digital environment. Anyone out there know anyone involved in the industry who might clarify things?

Try putting the ERS cloth over the breakers in the breaker box.
