Richard,

Just to supplement Nigel and Shawn's replies… there are no 20-bit CDs. To give it it's correct term, CD-DA has to conform to the Red Book (the book of specs. which encompass music discs) and that book limits the format to 16-bit. DTS discs are greater than 16-bit but they don't conform to the Red Book.

If you did have a 20-bit file on your computer, or a 16-bit file at 48kHz for that matter, you couldn't burn it to a disc and it appear as a CD-DA (the identification, emphasis tags etc., would not be recognised by players or burned at all). Instead you'd have to burn a data disc, keeping the file as a .wav or whatever.

: I am most interested in knowing if the new 96Khz tracks will still be at the proper bit rate if copied.

If you can extract a 24-bit 96kHz audio file from a DVD (and this is unlikely with DVD-A which will require handshakes between players and decoders) then you will only be able to burn it to a CD-DA if you first downsample to 44.1kHz and then truncate the word-length to 16-bit. Nothing I know of can do this.

Stuart.
