Are there any DIRT folks around? My sling on my 722 has stopped working - happened at the worst time, while I was on the road. Came home and tested: the light does not come on when I plug it in (and I tried both USB ports) and no message on the TV when I plug it in. I tested the USB ports themselves by plugging in my external USB HD, and it works just fine, so it is the Sling. Hard to see what could go wrong with it, since it looks like a thin solid metal slab! But it definitely is no longer working. I am asking for DIRT help just because I called and got someone who was quite nice but their accent was so strong I simply could not understand them. Thanks!
