Para todos los que tengan dudas de si el stick usb para ver la tv funciona y como, aqui dejo el extracto de la web en EEUU, esta claro y conciso..
Si alguno pregunta otra vez sobre este mismo tema, me hago con los derechos de esta web, despues me quedo como webmaster y luego lo baneo..

Dual-dongle supported: compatible models of Dune players (see above) can work with two Dune HD Digital TV Sticks at the same time. In such a case for example one of the dongles can be used for writing contents from some channel to HDD, another one at the same time is used for watching any other available channel.
This product doesn't contain any software.
All the needed software for operating the included Dune HD Digital TV Stick and working with channels is a part of the firmware of the compatible Dune players (see above).
The first version of Dune firmware supporting Dune HD Digital TV Stick will include basic work with channels (inc. TV programs recording to HDD), but supporting EPG will be included into the future versions of the firmware.
You can use this equipment with a PC on your own risk. No support for such use is provided.
