Delivery was the very next day, as it should be.
The supplied antenna for DVB-T is with me at the moment fully adequate (70-78% transmission strength).
The software DVBLink must be downloaded from the manufacturer's website, since there the version 5.1 is available
(You should advance to DSM5.1 xxx update its Disk Station and then DVBLink 5.1) so that the drive is supported.
Then TVSource install, and already the stick is detected. Start channel scan, configure channel list and Done.
Runs great with Smart TV's support DLNA, and Android devices. XMBC or like I did not need.
