Not exactly, as that would imply a unitary rx/HDD. To further the point, does connecting EHD to a 222 make for dual HD recording? Regardless, yes, there are definite constraints as far as using a 211- adding the EHD makes it DVR-capable, but only a single channel may be tuned at any time, either for viewing or for recording. No watching one thing/recording another or recording 2 at same time like with a 612, 622 or 722. Yet still if recordings are being saved in a 211-connected EHD I don't see any technical reason those recordings should at any point go away any more than they would for an EHD connected to and used with a unitary DVR model such as 612, 622, 722 (or hopper). Unless DiSH is indeed up to no good.
