Hi. I want to copy from my PVR to my DVD recorder/VCR combo. I have RCA cables going from the out ports on the PVR to the in ports on the DVD recorder. I have an HDMI cable going from the PVR to the TV and another HDMI cable going from the DVD recorder to the TV. I set the input for the TV to the PVR and play something. I push record on the DVD recorder. I let it record for 20 seconds. I then set the input for the TV to the DVD recorder and press play to watch what I just recorded and get only static. Aren't audio and video cables from the input device to the output device, all you need to do? What am I doing wrong? Thanks
