Grex

I purchased a Dimax Grex and cannot seem to get it to work. I have a Magnavox CMWR10D6 DVD recorder. My TV is older and does not have the proper inputs so I purchased a RF modulator so I could hook it up to the TV. My vhs will play through the dvd recorder ok but when I attempt to copy a protected tape it says I cannot copy that tape. I thought this unit was going to solve this problem. I have everything hooked up like Dimax said to. Can anyone help? Is there any phone number I can call for help?

Sounds like a hook up problem: VCR (yellow) > to Grex > DVD Recorder > to RF modulator > TV
