Does anyone know if a typical DVD video player (with a "96/24" D to A converter) can decode PCM tracks at the 88.2k sampling rate?
I know they'll play 96/24 PCM tracks (as Classic and Chesky encode on their DAD disks) but I'm wondering if 88.2 would work.
The reason for the question is I'd like to take some hi-res (88.2/24) recordings and put them on a DVD-R's PCM tracks for better results than I can get than if I converted them into 44.1/16, CD tracks.
Thanks,
Barry

For anyone who is curious, I've found that the DVD-V standard allows for sampling rates of 48k and 96k, at 16, 20 or 24 bits.
So the answer to my question is:
No, 88.2k won't work. DVD-V players will need the 88.2k material converted to 96k in order to play it back on the PCM tracks of a DVD-R.
The upshot for me is that I'll make my recordings at 96k/24bit so they'll be playable on any DVD player.
Thanks for all the input.
Happy Listening!

The processors in some DVD players may not accept 88.2kHz for decoding. However, most of them should allow for output via coax or TOSlink for decoding by an outboard DAC (as long as they also output 96kHz). I'm pretty sure the MSB Link DACs have 88.2kHz as one of the input lights.
Only a possibility, but...
You might be able to get an answer from John Atkinson of Stereophile. Many of the Stereophile recording projects were done at 88.2kHz and downsampled to 44.1kHz for the CD version. John may have burned some of these 88.2kHz recodings to DVD. If he did, maybe he can let you know what DVD player he uses to play them on.

If a player handles DVD-A, then it will incorporate 24/96 PCM capability. However DVD soundtracks are at a lower sampling rate. They might be upsdampled internally to minimise bit loss but outputs from players will be either analog or redbook digital. The higher resolution digital signal is encripted and cannot be copied unless you have underground code breaking software. So, the short answer to your question seems to be that no, you cannot easily (and legally) do what you are suggesting.
That said, if the analog out is fine (as it should be), you will get fine results from appropriate CD recording hardware & software.
I presume your copy would be used on lesser than your main system so my guess is that on this lesser equipment you would never detect any differences anyway.

  Hi John,
  Perhaps I wasn't clear.
  My goal is not to copy existing disks but to make new disks of original material. Instead of burning them to CDs (at 44.1k, 16 bit), I want to use the PCM audio "real estate" on a regular, DVD video. This will be playable on any DVD player with no need for a special DVD-A player.
  I know I can do this with 96k, 24 bit material and wondered if anyone knows if current DVD video players (96/42 equipped as most are) can also decode 88.2k samples at 24 bits.
  Thanks,
  Barry

    I'm not sure if this will help or work for you.
    The Calif. Audio Lab's CL2500 DVD player will upsample 16/44 material to 88.2k. It then outputs this signal thru it's analog outputs or it's AES (Balanced) digital outputs.
    If you choose the analog outputs, you will be running the upsampled signal (88.2k) thru the 1 bit delta sigma dac's in the CL2500, if you use the balanced digital outs you can send the signal to any componet (Dac or CD burner) you wish that can accept the higher rates.
    
    There are 2 CL2500's for sale on A/gon. One is $850 asking the other is asking $788. Also bear in mind that Cal. Audio Labs is out of biz, but still fairly easy to get service and repair for.

      Thanks dhrab but again, I'm looking to encode original material that was recorded at 24/88.2. I don't want to upsample.
      I'm trying to find out if standard DVD players (most of which have "24/96" D-A capability) will also decode 88.2.

        Another possibility: If you can find a DVD player which can read and output the 88.2, the Outlaw 950 preamp/processor and decode it. I have a Panasonic XP-30 which upsamples and outputs 88.2 into my Outlaw with excellent results.
