I have a converter box but I'm uncertain how to connect it to these other devices. Here is the current setup. I have an old syle TV without A/V jacks. The antenna goes into the VCR, from the VCR to an RF modulator, from the RF modulator to the Direct TV box. The satelite cable goes to the Direct TV box, and from there to the TV. There are audio / video cables connecting the RF modulator to the DVD. There are no other A/V cables connecting any other equipment. Can you tell me how to change this setup so I can add the converter box correctly?
