My dad wants to watch his recordings from his 722 on the road in his RV. He does not want to take 722 with him, or use sling. My thought was transfer recordings to an external hard drive and watch them on a 211k. The question is, the 211k will not be hooked up to a dish while on the road, does anyone know if the 211k can access the hard drive without being hooked to a sat dish? The 211k will be hooked up in his house when he is not on the road to keep up to date.
