    Anyone out there manage to successfully output 96K from a DVD-A player into the DSP-A5? Pioneer 575 is the player, sounds great through the ext decoder inputs for both 2 channel and 5.1. Was kinda curious to hear how the Yamaha dealt with the 96K as digital. But it just displays PCM 96K for a few secs, then flips to Dolby Digital / silence. Strangely even if I configure the 575 to downsample to 48K it does exactly the same thing. Suppose the D/A conversion needs to happen sometime and the Ext Decoder sound is great, but basically the 96K digital input "aint doing what is says on the tin" ;)
    Cheers...PJ

    It's not the fault of the player or the DSP-A5.....

    The Pioneer will not output DVD-A via it's digital outputs....only the i-Link equipped Pioneers will do this,and the DVD-A is output as an encrypted data stream to a suitably equipped Pioneer receiver with i-Link as well.
    This ensures that the data stream is encrypted up to the point of decoding and playback,and is in line with the DVD-A forums views on digital rights management.

    Thats the reason that downsampling will not work either.

    Denon have a similar proprietary link with some of their receivers and players,but other than that,all the decoding is done inside other players.

    Thanks, that probably explains it.
    Only part I'm unsure of is that I think the 575 does output 96K to the digital co-ax, it says so in the manual (but when has that been definitive? ;) ) but the fact that the DSP-A5 momentarily detects 96K seems convincing. But as you say it must be encrypted hence why it immediately gives it up as a bad job.

    It may output upsampled CD at 96kHz,as some other players do,(with varying degrees of success in providing any improvement in sound quality),but it won't be outputting DVD-A.
    What this may mean is if you select 96kHz output,then you may get a momentary detection of a signal,but the player will block output of DVD-A data.
    The Pioneer 757ai and 868AVi both have the i-Link facility,but this will not interface with your Yamaha.
