This product is suposed to be a DVB tuner. It is almost a good one under Microsoft OS, if you find a driver that works, which was difficult. Some of them are suposed to work on linux, because the hardware is generic and compatible (LiteOn) and has a driver included with recent kernel sources. However, mine refuse to work, because it is made such a way that udev cannot get enough information from sysfs to do it's stuff. Never succeeded in uploading the firmware anyway.

Works fine after following this howto http://www.fedorawiki.de/index.php/Intuix_S800 (it's in German, but you can understand the console commands).

Out of the box support. Just Plug and Play
