Technically, DS isn't a DVD-A (even though there is a Blu-Ray available for it), which is why I didn't buy it, but since WHBWH is a DVD-A with a Steven Wilson 5.1 mix, that's why I bought it. I haven't played it that much, but when I have, it's always been an enjoyable listening experience for me.
Oo... You right! DS are un DVD-V! Hopefully DTS.
