    How does my jvc sa70bk dvd player determine whether to play the dts or dolby sound track? Do I have to manually select it in the player setup as well as the dvd? Is there a way for this to be done automatically?

    Does the dts sound track require that PCM, Stream/PCM, Dolby/Digital/PCM, Downmix, Compression, DTS Bass Management all be changed from dolby sound tracks??????

    I think this is mentioned in the FAQ at the top of the page if you want further reading.

    DVD player:

    - Must have DTS bitstream output enabled (go into player setup per the user manual)

    - Must have DTS soundtrack selected (selected on the disc's menu)

    Receiver:

    - Digital connection must be made from the player to the receiver (single cable).

    - Digital input must be assigned to the correct video input (i.e. coax #2 = DVD player). Note: not all receivers have this kind of setup.

    - Must be set up to receive the DTS digital bitstream (usually DD/DTS is selected as the sound format). PCM = CD redbook audio.

    Once you have all of this setup correctly, you will only need to select the appropriate audio track on the DVD (this can't be done automatically).

    Brad,

    You have to select the soundtrack manually. Default is determined by the disc, so every disc defaults to different tracks.



    I don't understand the question (and from your mixing of terms, I assume you don't either).

    If you have a receiver, you set the player settings correctly to pass digital signal- and the receiver does the work. PCM/Downmix/Stream settings don't change (these are player settings that stay the same once set)-- and bass mgmnt is handled by the same circuit for dd and dts. Compression- DTS doesn't offer DRC.

    If I didn't answer this well, please feel free to rephrase.

    Yep.

    Once all the settings are right in the player and in the receiver- everything will work automatically. The only user intervention will be choosing the disc audio from the DVD menu.

    These are the JVC sa70bk settings I have questions about. I want to set the dvd player properly so that all I have to do is choose the audio track (dts or dolby) for each individual dvd & it is complete.

    DIGITAL AUDIO OUTPUT: PCM or Stream/PCM or dolby digital/PCM

    DOWNMIX: Lt/RT or Lo/Ro or Off

    COMPRESSION: On or Off

    DTS BASS MANAGEMNT: Of or On

    SPEAKER CHANNEL SETTING: 5.1 channel or expert

    SPEAKER SIZE: Large or Small

    Well, Downmix, Compression, Bass Mgmnt, Channel Setting and Speaker Size will only effect the analog outputs on the player. These features will be duplicated in the receiver portion, and these features on the player will be bypassed if using the digital output.

    The only issue of concern will be the Digital Audio Ouput setting.

    PCM will downmix the Dolby stuff and pass it as a 2 channel PCM signal which can be recognized by some digital products.

    Now, the other two are a bit of a mystery. Normally the digital passthrough will be the setting of "bitstream"- which would pass Dolby, PCM, and DTS as digital info to the receiver. I would guess that this would be the right selection.

    However, the Dolby Digital/PCM setting is a bit confusing. My guess would be that this is a passthrough for DD format and would convert DTS to PCM (or remove it entirely). Since most players let you turn on/off bitsteam passthrough for each format- I would assume this is your player's way of turning "on" DD and downmixing/disabling DTS (for those who don't have DTS support on their receiver).

    So, my guess is Stream/PCM would be the right one, you might need to try each of these two one at a time before you find the right one. Maybe someone with this particular product can explain the difference between the two settings...

    Once you find the setting that offers the digital passthrough to the receiver properly- you just leave it on that setting and all is well.
