In my 2 year old laptop with Wind.7 x64 doing the CSL - DVB-T USB 2.0, what it should. Better than the rod antenna with the predecessor product of Asus is included here thick antenna, by means of which 50 channels were recorded, of which less duplication and sales channels about 30 remained useful. Excellent is the reception quality. When all transmitters tested to this effect was at best value. Bad is that the registration code for TotalMedia 3.5 is squeezed in very small print on the extreme edge of Installatios CD case, so you can easily miss it. The part in bold and placed conspicuously. I was about to return the part until I finally has discovered the code. The downloadable instructions for TotalMedia is often too unspecific hingerotzt and unloving. Therefore only 4 stars for an otherwise good product.The Instructions for integration into the Windows Media Center is well done, but unfortunately is the win. Media Center not as clear and concise as the program TotalMedia 3.5.
