DSD files and the Oppo

[Dapper7500]

I just discovered the MinimServer a few days ago. It is the best I've used so far and not nearly as complicated as others I've tried. I am using it with my Oppo 103, and it streams my multichannel DSD files (dff and dsf) perfectly. I have three general questions/observations:

1. The files show up in the Oppo browser on my TV as "APE" files even though they are dff and dsf. They play fine when I select them, and are streaming as DSD according to my receiver.
2. The album art doesn't show up for any of them.
3. They will only play when I use the Oppo hardware remote, and will not play when I try to select them in the Kinsky app on my iPad (although they do appear as dff and dsf files in that app). It looks like this is the issue that is being discussed above.
