Blu Ray and HD, whats he best audio format?

Question

I have an HD DVD player and recently added a Blu Ray as well to my setup. I am confused about the new hi def audio formats and was wondering if someone could explain them to me. I was under the impression that DTS- HD is the best, with Dolby Tru HD next in line, than PCM uncompressed, and finally Dolby Digital Plus. Is this correct, or is there features that some offer that are better than the others. I guess I also don't totally see the difference between PCM, Tru HD, and Dolby Plus.

Thanks you!!!

Answer 1

Most receivers can't decode DTS-HD or Dolby Tru HD. So you need a suitable receiver for those. These codecs use lossless compression for multi-channel audio.

PCM is usually two-channel audio (uncompressed).

Dolby Digital  or DTS is multichannel audio using a lossy compression scheme.

Lossless is  better than lossy, but very few people can tell the difference, especially with low-quality speakers most of us have.
