Have been a Dreambox DM8000 used, running the same Linux operating system (Enigma2). While the DM8000 both SD as well as HD channels provides very good picture quality, this is shockingly bad with the two tuners of Duo2. Especially HD channels are almost completely pixelated and unusable. This applies to both the Free TV (ARD, Arte, etc.) as well as the pay-TV offer of cable Germany (TNT, SyFy, etc.). After some research in various forums, I realized that there are probably two different manufacturers for DVB-C tuner is - LG and Samsung. The poor reception quality supposedly only affects the tuner from LG. Had Well, bad luck. Within the return period returned again. If just continue the meantime something slow DM8000 used.
