Today I bought the machine, with a little stomach ache, because it is just written repeatedly by poor transmission characteristics or poor image quality. So unpacked and connected device, is really very simple. Sky-Receiver is in the living room, Scart plug in, antenna roughly aligned toward the bedroom, finished. The bedroom has 2 rooms and walls, though at the same floor, plug it to your TV, also finished. Then the surprise, it goes right away, the picture quality is my feeling after very well. The TV in the bedroom is a 70 cm widescreen (tube) of Philips. The only downside, so a star deduction, the IR control does not work, Maybe it's also on Sky-Reciever.
In any case, it is put in a very convenient alternative to 20m HDMI cables and drill through 2 walls.
Addendum: After request from One For All because of inkombatibilität the FB of Sky I was told that the device is replaced with a new unit within the warranty period. No sooner said than done, within 1 week there was the "new" device and it runs all the best. Therefore, 5 star and for the great service it would have to again give 5 stars.
