My JVC RX-6010VBK HT Receiver has a "Monitor Out" jack. I'm not using it because I'm not sure what it's for. My TV has only a coax input so I go composite from the DVD Player to an RF modulator and into the TV. Where does the Monitor jack on the Receiver fit into this? Or does it? The Receiver also has VCR input and output jacks. I'm guessing that they are somehow related to the Monitor Out jack. Thanks.
