First let me apologize if this has been covered. I have a round dual LNB Directv sat w/ an 8 out multiswitch that operates 5 receivers. I do not have HD nor do I plan to have it for a few years (also none of te other special programming). I am considering adding a dvr but I only have one cable to supply to the dvr. The dvr will be in a loc where running another cable is not feasible. I am considering buying a stacker and stacking 2 outputs from the multiswitch and destacking at the DVR if necessary. Can somebody please review this and tell me if this will work? Thanks.
