Have seen in in other posts a lot of you guys have a device called the JS Box RGB to Component. I am slightly confused about what this does, and if it will be of any benifit to my setup of a Pioneer 433HDE, Marantz 7010 DVD and Sony Sky digital box. So if anyone has one and could answer the following i'd be very grateful. 1.Does the box connect or convert RGB to Component? 2.Is the difference in picture quality noticeably improved with the box rather than just connecting RGB to RGB. Thanks.
