Yes only movies with subtitles. My /etc/exports appears fine, but I'm not sure what it means by the following section:
## BEGIN : InternalStorageDevices
/mnt/device/99 192.168.80.0/255.255.255.0(rw,no_root_squash,no_all_squash,async,nohide,no_subtree_check)
/mnt/device/100 192.168.80.0/255.255.255.0(rw,no_root_squash,no_all_squash,async,nohide,no_subtree_check)
/mnt/device/127 192.168.80.0/255.255.255.0(rw,no_root_squash,no_all_squash,async,nohide,no_subtree_check)
/mnt/device/99 is the primary storage, but the others I am not sure of. There is nothing in those directories anyway.
