Hi Jason,

Is there any written report substantiating these claims?  I would be very
interested to see that!

Proof is such a strong word, especially when accompanied by a word like
definitive.  Subjective tests for assessing video coding impairments are
time and labor intensive.  I'm curious what kind of tests were run.
