Subject changed because people misunderstood it
Man, I'm frustrated with Rockbox. I have the latest build (r21127) and the database still doesn't work. File navigation is useless, since the interface doesn't seem to react well and it doesn't show the music directory. That leaves the playlist, which it occasionally doesn't recognize the one that's on there.
Now the latest problem is that Media Center can't seem to recognize the music that is already on the device
Right now, I don't know how anyone can look at Rockbox and declare it usable.
