Howdy! I've recently installed my 990 and am looking for a bit of advice about DD, 990 & DVD configs- I also installed a new Oppo DVD player- It's optical output choices are PCM or "Raw"- It apparently won't output DD unless it's set to "raw" but the 900 doesn't seem to "like" the setting- Set to raw, the audio drops out, occasionally making various random hi-pitched "squeaks & squeals" before it does- Set to "PCM" the 990 only plays back in Dolby PLII mode. Any thoughts or experience about this? Thanks in advance.
