"| OTA has much more data and is not compressed. Satellite's picture is fine, but it is still compressed. Cable, from what i have seen is even worse. In other words it is more difficult to see the difference between sat and OTA, but there is a noticible difference between cable and sat."

I couldn't agree more. My brother installs cable for a living and he'll tell you like it is...even HE doesn't have cable.
