ok wanting to purchase another receiver and cant decide between 211 or 222. i want to control 2 tvs but also want dvr capability. i currently have a 722k for my hdtv and standard tv but will be adding another hd tv and standard tv as well. could i get the 222 and add external hard drive or can i get the 211 add the harddrive and just splice the signal from the 211 to another tv? any help would be appreciated. thanks.
