In our area, channels above the teens are considered "cable", as they would be in most places. The service is Family(sans box), with channels 2 - 80 provided.
The issues are herringbones and ghosting that appear on ch 15 and up, nonexistent on some, horrible on others. However, when viewing the same channels via the Insignia home theater one-piece(DVD-VCR-amp) all channels are crystal clear - 3D clear to be exact.
Is the issue the TV?
Thanks,
