Just had the H20 installed in my bedroom and I am loving the HD. However, I am having a problem with the remote issued by Directv. My installer set up the remote to my Westinghouse tv and the volume works and the tv shuts off when the remote is in the tv mode. However, the Directv and tv off button will not shut off the tv. This frustrates me and the wife. Could it be a wrong code? Bu that makes no sense since it does shut it off in tv mode. Help and thanks in advance.
