LS421 DSD Playback

[Metty]

Hello,

as I cant find any documentation on the DSD-Playback Topic, I have some questions of understanding and I hope someone here is able to enlighten me. I am also not too familiar with all this stuff, so dont judge my noobish questions ;-)

The feature is described as:

Stream digital music in studio quality - the LS400 series has the Direct Stream Digital (DSD) playback and streams high-end audio files without losing quality. Buffalo is working together with major audio equipment brands to ensure compatibility with most network-capable AV receivers, players, and streamers and DSD-native and DSD over PCM file formats.
- DLNA media streaming powered by popular TwonkyMediaServer 7.1
- Compatible with Hi-res audio such as WAVE, AIFF, FLAC, ALAC, DSD64(2.8MHz) and DSD128(5.6MHz)

The compatibility List says the Denon AVRX2000 is compatible, thats good, cause thats the one I have.

Now the questions:

-The TwonkyMediaServer 7.1 mentioned is the DLNA Server running on the Linkstation anyway, or is it something that needs to be added?
-The Denon AVRX2000 is not a DSD-native AVR, when I play SACD, the player has to give out DSD over PCM. So when it says DSD over PCM is supported, does that mean the DLNA Server converts the DSD to PCM, so the AVR can use it?
-So when I download some DSD64 .dff Samples from http://www.highdeftapetransfers.com/page.php?wid=27, put them in a folder that is used for DLNA on the Linkstation, my AVR should play them, cause the Linkstation converts them to PCM?

As you can guess, the reason I am asking is because it is not working like that. When I try to play the files, the AVR gives out a file format error message.
