This is only partly true. Since cable has a higher signal to noise ratio than OTA, they can use QAM256 and get more data through
the link than 8VSB, so potentially they could send 2 HD signals in the same bandwidth that would allow only one for 8VSB at
about the same quality.
But then comcast goes and tries to cram 3 HD signals in that bandwidth.
