4 * and not 5 because the channels in HD (1,2,6 ...) are for me and not in DVD quality in HD on my TV as (USB key plugged into a laptop computer with full HD !!)
Very good product for those who want TV on their computer.
Remote control included with 2 CR2032 batteries (not very standard) and it must be close enough to the infrared receiver to Work with Media Center (W7).
Needless to remind that the supplied antenna is absolutely worthless if you do not live in a TDF transmitter relays, so you need to connect an antenna wall the key ...
In summary, very good investment to have an extra TV on your computer with MCE (Media Center Edition Windows 7) !!!
