We determine the decomposition of V[sub √2D[sub l]] into a sum of irreducible T-modules for general l where D[sub l] is the root lattice of type D[sub l] and T is the tensor product of l + 1 Virasoro vertex operator algebras with central charges c[sub l] = ½, c[sub 2] = 7/10, c[sub 3] = 4/5, and c[sub i]=1 for 4 ≤ i ≤ l + 1.
