Does anyone have any experience recording programs via 211K using a USB plug in hard drive? I have a space limitation for a receiver in my motorhome and the DVR units are too large. According to the Dish salesman he said this is possible. Is this a novelty or real or another Dish information mistake? Does the 211K actually have a USB port? If possible, is it pretty easy to record future programs and play them back similar to the DVR receivers we have in our home? If this works, will it record both HD and SD?
