They weren't in HD, they just filled the screen. I know several of the SD sub-channels in my area that I record some old shows from does that with some of the commercials. While most of the shows and some of the commercials are in the 4:3 aspect ratio. Many of the commercials are in a 16:9 aspect ratio.
