Well I did a little searching and found on the Oppo 93 it says the auto setting for dynamic range does nothing with dvd playback but with Blu-Ray it gives the disc its proper dynamic range.Not sure if it does the same with Oppo-83 or even what proper dynamic range on a Blu-Ray means.Does it limit or enhance dynamic range and what criteria does it use to determine this?

I don't know but it would only apply if you're using analog outputs. It should have no effect on the digital interfaces.

^ Dynamic Range Compression is applied during the decoding of Bitstream audio. So it applies to the Analog outputs and also to HDMI LPCM output of Bitstream tracks.

It uses meta-data found in the Blu-ray tracks. The problem is, rather a few discs have been found to have bogus data -- leading to anemic dynamics if you leave Compression on.

My recommendation has always been to leave Dynamic Range Compression OFF in the OPPO. If sending Bitstream to an AVR, look for a similar setting in the AVR.

If you find a disc really is too dynamic for comfortable listening (with knocking the neighbors out of bed), then turn down Main Volume or go ahead and re-engage Dynamic Range Compression.
