I'm getting Directv installed this Thursday. It says 3 Hd plus dvr's and 3 lnb's on the order that they sent to me. Is it possible to have the wall plates installed and how much extra will that be? I'm not crazy about having holes drilled in the ceilings in the closets. Is there any way of finding out exactly what dvr's i'll be getting and whom in my area will be installing it? I appreciate any suggestions or advice anybody can offer.
