The media center software XMBC is available on the OUYA gaming console. With it, you can watch movies, play music and view images stored in your network.
Most of the files I have are stored on a Synology DiskStation (with two parallel disks for data safety) and are exported via NFS to the clients.
XBMC (now dubbed Kodi) is able to mount NFS shares, but it did not work out of the box. Fortunately, the Kodi NFS wiki page tells us what's needed: The options in /etc/exports need to be ro,all_squash,insecure. Unfortunately, the DSM does not allow to set the insecure option on NFS shares.
So I had to log in as root via SSH and edit /etc/exports with vi. The following export works fine:
/volume1/media 192.168.3.32(ro,sync,no_wdelay,all_squash,insecure,anonuid=0,anongid=0)
After changing, you have to activate the changes with
$ exportfs -ar
Editing the shares via the web interface will reset the options :-/
