here what i got! The installer install a 722k dvr and a 222k. they are both dual tuner just on does the recording (722k). so i have the 722k in the living room then is back fed to the tv2 up stairs, Same way with the 222k hd down stairs and standard tv upstairs.Now tv1 and tv2 on the 722k get dvr service. its there a way i can run a cable to my tv ant input then attach it to the tv line on the diplxer for the tv 2 with a 3 way splitter, would that give me that i can watch the dvr programs in the two other room with with the 222k?
