This would need 8 x 2^{64} bytes of storage which is approximately
2,000,000,000 DVD's (~ 4 x 2^{32} bytes on each).

Probably, you are referring to the fact that during encryption of a
whole DVD, say, in CBC mode two blocks are likely to be the same
since there are an order of 2^{32} x 2^{32} pairs.
