To the best of my knowledge, both the SACD and the DTS-CD contain the same identical surround mixes. The hybrid SACD version was originally a single-inventory item, so there may be quite a few copies floating around---on the used market, if nothing else. Just be sure to look for the SACD logo. Both the multi-channel SACD mix and the DTS-CD mix have mediocre sonics/fidelity, yet they are still quite tolerable. And the surround sound can be enjoyable for someone who doesn't mind a lot of direct-radiating sounds coming from the rear speakers. This is essentially a greatest hits album, so I'm happy enough with it.
