Yeah, the guide said to do it because it makes it easier to manage via Android, but not sure I'm going to do that anyway. Setting it back to auto seems to have fixed it!
Now I just need to figure out this slight stutter I am getting. Watching Brave, full BD MKV rip. Switching from the TrueHD to the DD+ makes it near perfect, but it still pauses real briefly about every half minute or so. Someone elsewhere suggested using NFS connections instead of SMB, but I'm really clueless on that. One thing I read though is that NFS doesn't work with FlexRAID, so that might make that a no go.
