    My new DVD player output the normal PCM, DD and DTS.

    But it also outputs 96khz and MPEG

    What are these modes used for?

    MPEG encoded audio is pretty much obsolete now due to lack of support/interest having been usurped by DD and DTS. 96K sampling rate is less common on DVD players - most down-converting to 20/24Bit 48KHz max - and allows you to send DVD-Video's max 24/96KHz data-stream to an external DD/DTS decoder, or say a 96KHz DAD to an external DAC such as Musical Fidelity's X-24K DAC.

    Thanks for the info...

    What media would be encoded with a 96Khz bitstream?

    Are we talking HDCD?

    Dont think HDCD would carry 96khz as this would break the CD standards.

    There have been some music only DVDs released which contained a 96khz PCM track (IIRC). These were marketed as DVD Audio discs but were not official DVDA standard.

    Havent seen many new releases for some time though so they may have been dropped in anticipation of proper DVDA discs.

    They were actually called Audio-DVD and I have one for which I payed a premium - and never listen to it again because I just don't like the music on it ... :(

    Gentlemen - sorry for re-iterating any of your points.

    The only option for accessing existing 96Khz material is via the old DAD discs which are 24/96 encoded (2 channel stereo for DVD-V - damn fine sounding too I may add) or the newer DVD-A standard which were meant to include 24/96 tracks available for existing DVD-V owners but in the event only included 5.1 mix tracks for DVD-V owners at 48Khz, I dont know of any new DVD-A tracks which are upsampled to 24/96 as promised.

    Duncan - you are correct HCCD, XRCD & other Hi-res CD formats are still only playable at 16/44.1Khz no matter how they were mastered.

    Jon - I take it you have a Pioneer DVDP which is one of the first manufaccers to include a pure 24/96 PCM datastream from its dig output. As ZeroP says this 'pure' datastream is quite important if you wish to add an offboard DAC at a later stage. Something I would say to anybody wishing better hifi from their DVD-V is to do this I did and it is fanstastic sounding (I added a MF X-24K) rather than adding a separate CDP.

    BTW IMHO - the DVD-A industry has lost the plot looks to me like the SACD hi-res is the way to go, all they needed to do was to include 24/96 DVD-V playable tracks and the format would take off. As everyone with a DVD-V player has compatable 24/96 DACs already.

    Reiner - we seem to have posted at the same time - your quite correct - I paid £24 = £3 p+p a lot of lolly for a DAD disc in my book, which whilst sounding great isn't worth 3 normal CDs in anyone book.

    CJCROSS, I don't know what a "Pioneer DVDP" is.. I have a Pioneer 545 which has an option for 96khz output as 96khz, or downsample to 48khz.

    All the best

    Jon, what player did you have before? What do you think of the new Pioneer 545? Does it beat your old player noticably by picture and sound?

    Thanks

    Gareth

    just my way of saying DVD players just CDP.
    BTW set your PCM to 96Khz for optimium sounding playback with normal CDs.
