    If I have a DVD88 Plus and an AVR200, is there a way of selecting which one decodes DD/DTS sound, it's not clear as both suggest they are performing the decoding of material. Is there a difference when using the co-ax or phono out connects?

    Hi Malcom

    If you use the analogue outputs of the DV88 then the DV88 is doing the decoding. If you use the digital output of the DV88 then the AVR200 is doing the decoding.

    Some people say the AV receiver is better at decoding than the DVD player. I would try each and see which you prefer.

    Hope that helps

    The DV88 Plus does not have Dolby nor DTS decoders. It just outputs the DD/DTS multichannel bitstream via the digital connector(s) and the AV200 receiver does the decoding. The phono out connectors output a analog stereo soundtrack.

    Typically, CDs will sound better using the nalog stereo outputs. With DD/DTS movies you'll want to use the digital output since you have a DD/DTS surround receiver.

    If you want a player with DD/DTS decoders builtin, you'll need one that is DVD-A capable (DV89, DV79, DV27A, DV29), or have your DV88 upgraded to DVD-A (making it a DV89).

    Thanks,

    The reason I'm asking is because I'm having some problems with Dolby Digital material. After warmup (20 mins) a DD soundtrack exhibits some high pitched noises from all speakers, whilst this is not evident on the same disc outputting a DTS sound. I've tried another DVD player, same, changed to outputting thru the phone, not high pitched but there definately is some crackling going on. I wondered if I could switch to check out whether it was the DVD player or the AVR causing the problems. (although AVR has been back to ARCAM for a new board). From the replies, it would appear it is the digital output stage of the DVD player? This sound reasonable?
