I have to hook up a digital box for my mom this weekend as she no longer receives any channels above channel 21. I haven't seen the digital box, as it is at her home. Do you know if the digital box comes with the necessary cables to complete the installation from the wall cable to the VCR and the VCR to the TV? The installation instructions look very straight forward, but is there anything I will have to do to make the remote work? Is there anything else I should know? Thanks so much!
