Yes, the AR in those screencaps doesn’t match, but what I’m saying is, if you shaved eight pixels off the left and right of the GOUT, then stretched it back out to fill the same rectangle, it would be a much closer match – and that’s how it would have actually looked if you watched it on a TV circa 1993 when the master was made.
Most DVDs get too tall and skinny when you watch them on a computer, or over HDMI. It’s not specific to the GOUT.
