Dolby True HD vs. DTS HD

There is no answer that is true all of the time Tlg. Most of the time DTS HD is better and uses less compression. But in some cases D True HD sounds better. It's easy to compare if your Bluray remote has an audio button as most do. Just start the disc and switch back and forth while it's playing.

Is War of the Worlds out in Blu Ray ???

It's coming out June 1, actually.

So you can't have tried the audio on lossless then - maybe you were switching between DTS and DD, hearing dynamic range compression in DD or even just differently mixed volumes.

BTW, I have A-B tested War of the Worlds and yes, it is more 'dynamic' on lossless format, not necessarily louder though.

Since "War of the Worlds" won't be available on Blu-ray for two more months, what *are* you talking about?

BTW, you're right that the Marantz should be able to decode multi-channel PCM, though it's limited to 5.1 unless it's had a firmware upgrade.
