To connect a digital HDTV to a tunerless DVD recorder, first connect the cable box to the RF modulator using the RF output. Then, connect the RF modulator’s output to the DVD recorder’s AV jacks using the appropriate cables (typically composite video and audio cables). Finally, connect the DVD recorder's output to the HDTV using HDMI or composite cables, ensuring both devices are set to their corresponding input/output settings for proper signal transmission.
