The DSD4121 high-definition set-top box now has embedded software that can be activated to convert the unit into a Digital Recorder. An External hard disk drive ( powered via mains ) is required for this function. The USB port is used to connect this externally powered hard drive and with a new remote control the DSD4121 is able to record your favourite in digital format.

You need to purchase a remote control and a special code is required to activate the software that is in the decoder.
