DLNA (uPnP) doesn't support streaming of DSD files directly, they would need to be transcoded to PCM. With SMB sharing you can see DSD files with a Oppo 103/105 series, same with attached storage (thumb, external HDD).
The DoP (DSD over PCM) is used with the USB DAC input on the player if you have a BDP-105D. The BDP-105 supports only PCM up to 192khz sampling, the 105D supports DSD64, DSD128 with a updated USB DAC interface. The 103/105 series only allows DSD64 playback from storage or SMB.
