I assume the Liteon DVD recorder is a stand alone set-top recorder and you want to connect it directly to the Cable Box.

Such a recorder does not have a TV tuner and is always set to channel 3 (it may have a switch that will let you select chanel 3 or 4).

If you have an old VCR tape unit, it has a TV tuner built-in. Connect the VCR to the cable box and then connect the stand alone DVD recorder to the VCR. The VCR will output its RCA connector as channel 3 or 4.

You will use the VCR to select the channels.

You will likely need to connect a TV to the VCR in order to get the VCR settings correct. Once they are correct, you can disconnect the TV and connect the DVD recorder.
