Same. I only noticed it for the first time last evening and watched / recorded the program about the search for the Japanese supersubs. (Saw the last half of it in primetime and decided I wanted to see it all so set it to record at 2 AM.)
I did notice that the SD (at least that show) is being rendered in a side-bar, letterbox form that when you expand it with the controls on the remote it exactly fits the 16 x 9 format. I like that! And the PQ was great for SD. (Size and quality comparable to what I sometimes see on IFC.)
