have you ever tried your card in any other reciever?
I dont think Zee tv cards are married to the STB (Zenega)
all you need is any emu at dreambox and that is it .
I have ****** II zee tv card which was supplied by the dealer saying it will only work in Technosat reciever. after an year I bought digital world and humax and it was working in those recievers
then i switched to sharing stuff with dreambox. first it didnt worked on dream i thought it will never work . but When i chanegd the Firmware to Gemini and Emu to camd or gbox . it worked,
SO i will suggest why not give it a try \
Install gemini 2.10 and then install Emu newcamd or camd . to see if its working .
after installing cam . press blue button go to cam selection menu . select your newly installed emu and then reboot or wait for some seconds for picture to come.
try that and let us know if that work.
Note : Zee tv card will not work with official firmware/emu supplied with the dreambox. you have to install any other firmware (gemini , davinci )and Emu (camd, newcamd. gbox)
