I use Time Warner cable broadcast basic service. My new TV has a low quality tuner that has light audio buzz on some channels. I am attempting to use a DirecTV box (from thrift shop) as a substitute tuner (without DirecTV service). My VCR does not have stereo audio output or I would use that. The box (DRD480RE) did not come with a remote. I have programmed a universal remote which works with some functions but I cannot figure out whether I can get a button on the universal to act as "Antenna" button. I am hoping this will get around need for an access card for simple broadcast service through the antenna jack. I am also willing to open up the box if there is a fix so I can just use the tuner. Any help appreciated. Thanks.
