you not need other app.
Well, that's debatable 
I would rather not have to switch between apps to control Q5/sound on Receiver...

Another quick question... My movies are on a NAS, how do I access them with the Q5? Thru smb?
yes, kodi + mediawrapper support only SMB( without password )
himedia media center support SMB/NFS/DNLA
