From NAS-Central Buffalo - The Linkstation Wiki
The Dbox2 is class of DVB digital TV settop boxes that are popular in Germany. To record digital data from a Dbox2 a LinkStation can be used. This was once the main reason for people in Germany to buy a LinkStation.
NFS needs to be installed on the LS for this purpose.
