I have a somewhat old Panasonic VCR attached to my 1070. If I watch TV using the VCR tuner fed through the 1070 to the screen the image is fine. If I patch the VCR out directly to the TV the recorded picture is fine. But if I play a videotape through the 1070 to the screen the color flashes in and out. I have tried using coax interconnect cables, as well as audio interconnects. There is no difference.
The issue is not what is being recorded on the tape and later played back, and it is not the signal getting to the VCR from the antenna. It is something that is apparently happening after the signal is entering the 1070.
Thanks, Bob
