I tried that for quite a little while. There is no way to set up the Replay for automatic recording for the OTA 6000 channels because the Replay doesn't know about those channels. So you're stuck with HBO, Showtime, CBS, and Discovery channel. 
I have managed to get scheduled automatic HDTV recordings working with the Samsung D151 OTA HDTV decoder, you can "fool" the replay into thinking it's an analog cable box and have it control the channel changes. This is on a recent thread here.
Hope that helps.
