I was just setting up my DVD player today and noticed I can set my digital out up to 24bit 96khz. Now I thought that the SPDIF standard was only up to 16bit 48khz. Someone please explain how this is...Don't DVD players encode their audio in 16bit anyways? Thanks for the help.

BTW, I have a 6.1 surround sound setup, would it be best to set all the output modes to Dolby Digital and DTS?

There is a 96/24. It's a DTS extension. Used, I guess, on some disc somewhere. You would enable it if your receiver also supported it. Unless you have a DTS 96/24 disc, I would not worry about it one way or the other

That seems like the most likely purpose of the setting from my experience.

As for S/PDIFs max PCM bit depth, I believe it's 24. But I am not sure how many receivers would allow 24.

As for the max PCM rate of S/PDIF, I am not sure it has one. As for whether any receivers support more than 48/24, I could not say.

S/PDIF can transmit 2 channels of 192/24 PCM. The DVD video format (not DVD-A) is spec'd for 2 channels of 96/24 PCM.

Set the digital audio output on your player to "raw" or "bitstream" or any setting that is not "PCM" (the PCM setting will convert all soundtracks to stereo).
