My nas was een ftp mount and It just gave a black screen after saving the paths, you mentioned something like that in the openings post.
As for the setup its pretty okay I just find ommpc in general a bit fiddly, but the 'h' key helps alot. Things I miss are stuff like pressing y on albums gives you nothing and I expected it to give a playlist sorted by album title. I miss a shuffle albums option (i miss that in most music players) because that's the way I listen to my playlist one album at a time. Also the enque option is a bit disorienting since it switches the song to the place where it will be played and you loose the nice ordered list in that way.
The rest is pretty nice, I like the big interface
For me the best option would be a huge audacious skin, or a better handling of files on my NAS by deadbeef.
(btw I have yet to come by a music player that really handles 30000+ files on a NAS wirelessly connected well even on my desktop, but the pandora is getting there)
