I had a new dvr box installed a couple of weeks ago and it isn't responding to the commands from my remote. I had the same problem with the previous dvr, that's why direct tv replaced it. For instance, when I am fast forwarding, I can push the play button ant it won't respond. It just keeps fast forwarding. It will not respond to any commands from remote. after about a couple of mins it will finally respond to the first command, like there is a huge delay. Any solutions?
