Hi,
The DVD player should have 3 lines out.
The colors should match up with the Modulator.
You will need an RF switch easly found in most department stores.
Run the VCR to one input of the switch and the Modulator to the other.
Run a cable to the TV's antenna input (if cable ready else you will
need an impediance adapter, once again easly found)
Run your Rabbit antenna to the VCR's antenna input.
One side of the switch will be your DVD the other will be the VCR and
local chanels.
