I have been experiencing trouble with my Dish DVR 942 and the tech support people recommend that I ensure that my wiring is grounded (the coax between the dish and DVR unit). I know I can use grounding blocks and hook into my house ground but this will be semi-painfull. Do surge protectors ground the coax shield? If not, is there an alternative method for grounding the shield (stick grounding block output into ground plug of a wall outlet, etc.)?
