I am wondering if anyone who has the newer HD box model HDS6300 also had the experience with the older models. My 3yr old HD box died, so I gave it for service and I was told that it is not repairable and that I should just get a new box. Interesting part is that I got a temporary SD box and the interface on this is much snappier than on the older HD box. I was always irritated by how it took one to two seconds on the old HD box before it reacted to my press on remote buttons, and wondering if they might have improved it on the new HD box model.
