Well yes,
if you re-encode your MKV to either DVD compliant or BD compliant video so that you end up with a "real" DVD-Video or BD-Video disc rather than a data disc containing just the original MKV.
But if you burn that very MKV as is, then it does not matter whether it's a DVD or BD media as long as it fits the disc and your player can play it.
