I dont believe it will work for you with Kabel Deutschland
you ordered "Sky Deutschland HD 19E" - especially 19E shows SATELLITE, not cable
I am not sure where to check this on a Dreambox/Enigma, on Neutrino(HD) you can open technical informations (default = key blue > key blue again) where you find the parameters, but I dont think you will find the CAID 1702 or 1833 in the list of CAIDs on Kabel Deutschland signals (as far as I know it was possible but changed/disabled by Kabel Deutschland within the last year - the SAT-CAIDs are no longer provided by Kabel Deutschland to the customers = not possible to decode - as you get no ECMs on this CAIDs you cannot decode using cards for this CAID. And a betatunnel is also only possible from 1833 to 1702 or 1834 > 1722, all other combinations are incompatible)
