I have a minor problem with this DVD Set, "Hockey: A People's History". For some reason, the video display width was incorrectly set to 640 when the MKV was created. The video display width should have been 853. I was able to adjust it within the MKV container, but I wanted to mention it, because the DVD plays fine and in the correct size using DVD player on my Mac.
