The receiver offers an excellent performance for this price. Since other comparable HDTV receivers that offer Linux as an operating system and Enigma2 as a graphic user interface, either are not sufficiently well or very overpriced, the VU + Duo due to good reviews was appointed in various forums. The receiver makes a very good visual impression, the mirrored black front gives the receiver an elegant disign. Likewise, the piano lacquer black remote control looks very good, plastic instead of rubber buttons have I personally liked better (but is also among the most expensive comparable receivers otherwise). The display of the VU + Duo also features a beautiful blue glowing impression, discreet and classy. The technical details leave nothing to be desired, unless you want to connect 4 satellite tuner. But with 2 satellite tuners, the box is always well prepared the same time to a plurality of transmitters that may be on two different transponders record. Here you can watch also easily other transmitters on one of these transponders 2 different times. In addition, the box provides 3 USB and 1 eSATA slot to which one can connect one or more hard drives, they are immediately recognized and most (or all the usual) video and image formats can be played back directly from the box. The hard drives can also be used to record to broadcasts. An internal hard drive can be easily installed without additional Accesories and put into operation immediately. What I do not like very much in the hardware of the box that you can hear the fan in the box operation machchmal softly. But everything else is very well resolved and there are many more than the above-mentioned features. The software can be easily installed on a USB flash drive or via an RS232 connection combined with a LAN connection. The software support for this box is excellent. Found defects in the Software will be corrected very quickly through software updates. Many different plug-ins can be downloaded directly from the Internet via the box and installed. Among them, for example, YouTube player, Photo Viewer, different skins, Fritz Call, VLC player and much more.
Totaly a very good device, which is probably unrivaled in this price range.
The picture and sound quality leaves nothing to be desired, as long as you meet the correct settings. The quality is usually limited only by the received signal, which is not, of course, on the receiver itself.
