Which DirecTV receiver are you using? You may be able to add the AM21 OTA tuner and use it to tune the OTA channels. The AM21 integrates the OTA channels into your DirecTV receiver and guide so they show up right next to the other channels, and you can tune to them from the guide etc. It wouldn't require hooking anything else up to your TV. To use the AM21 you need to have an H21, H23, H24, or H25 DirecTV receiver, or an HR21, HR22, HR23, HR24 or HR34 HD-DVR.
