Not all albums are showing from USB hard drive with Node

I just setup my Node and very few albums are showing that are on the USB hard drive. My entire Neil Young album library shows but not many other artists or albums. Many are DSD files of ripped SACDs. I'm using the optical output to a Marantz SA-KI Ruby player. I tried reindexing but that did not help. Any thoughts on how to get all the albums/folders to show would be appreciated. Thanks!
