I have a problem the the 981 HD with its RCA digital out when playing DVDs - it motorboats in synch with the platter motor.

Oddly the audio via external DAC is OK with CDs but not with DVD (Although the video is fine).

Audio out of the L/R analog (using the internal DAC) is fine for DVD audio, but not using an external DAC.

We have not tried it with Toslink but suspect that is the same.

I contacted OPPO for a service manual or circuit diagram but they refused, although offered to help if we posed questions. So far they are not responding.

Any suggestions or ideas where I might find an answer on the net would be appreciated.

TIA

John

What external DAC are you using? Not all DACs can handle all digital formats, and the digital audio on a DVD is typically a different format from the digital audio on a CD.

DVD uses Dolby AC3 or DTS digital audio. This is a compressed 5.1stream and cannot be input to a basic audio DAC. When you play a CD in a DVD player, it outputs standard 2 channel PCM which any DAC can use.
