Hopefully you’ll be using the Blu-ray release as source. Not the DVD.
There is no Blu-ray release.
You must be thinking of the 1990 series which is only on DVD and not the 2014 series. Because the first two seasons are on Blu-ray disc that I do own. Hell, Season One on Blu-ray disc is only $12 USD and Season Two is only $18 USD.
If you’re still supporting DVD when it’s dual released on BD, it’s hopeless you’re supporting an archaic format.
Though I wish the seasons were on 6 discs instead of 4. At least it has DTS-HD MA 5.1
