Macrovision is placed onto a VCR so that it can't record copy-protected DVDs from a DVD player connected to the "Video In" on the VCR. However, you can get around the Macrovision if you want to back up your DVD movies onto VHS (this is legal as long as you don't give the copies away or show the movies for profit). You can't use both VCR and DVD sides of the combo at the same time, so in order to record onto VHS you must connect a stand-alone DVD player.
Connect the RCA side of the 3.5mm to RCA cable into the "Video Out" port on the back side of the lone DVD player.
Insert the 3.5mm end of the cable running out of the lone DVD player into the "Video In" port on the video camera.
Attach the second pair of 3.5mm to RCA cables to the video camera. You want the 3.5mm end of this cable to connect to the "Video Out" port on the device.
Plug the RCA ends of the second cable into the "Video In" port on the VCR/DVD player.
Insert a DVD into the lone DVD player and insert a blank VHS tape into the VCR. Power on the lone DVD player, VHS/DVD combo and the video camera. Set the camera to "Record" mode (but don't press "Record").
Press "Play" on the lone DVD player, then hit "Record" on the VCR and the VCR begins to record the DVD content. This is because the video camera strips the content free of the Macrovision, allowing you to record the content of the video onto a DVD.
