ADS Tech Instant TV DVB-T USB
According to ADS Tech this product has been discontinued.
The device is based on DiB3000M-B (DiBcom USB1.1).
Note that USB devices are not working stably in a long term usage setup (e.g. with VDR). All of them suffer from random disconnects after a few hours or days. Therefore for a long term usage setup, use a supported PCI card instead.
