Picture and sound are top !!! The most importantly. Even and especially in non-HD programs (upscaling).
The shortcomings already mentioned here seem to come part of the faulty firmware. Those who expect easy to buy a device to connect and be satisfied - is not quite find it.
The referenced EPG with its dropouts is quite annoying. Here was once again (and make others see above) brought a device on the market, in which the software does not work 100%. As of today (17:01:10) is not even an update is available on the manufacturer's site. The last update had all their little quirks and were taken from the server. Update via satellite is currently not possible.
In hifi-forum.de you find much useful information concerning the firmware - what goes with what and so on.
The upscaling of SD programs is impressive well. The nonsense with the private and their patronizing ducks HD + waste remains a so spared. Who paid money deserves it no better.
From me, there are only 4 stars because of the still insufficient and the lack of EPG update that will hopefully resolved.
For the price and the power he actually deserves 5 stars.
Nachtag 20.04.2012: For some time the update runs to the receiver HD + to make runs on the receiver.
No, I use the useless HD + not. By updating the EPG is much better and also the menu is made up appealing.
Now everything works perfectly !!! Therefore, now also 5 star.
