I have dvb viewer too and it works great with and linux. At first controll your tapicolinux networkcard. Use the following ip adress: 192.168.11.1 subnet 255.255.255.0 and then gateway: your ip adress from your router and dns the same. Note: in your router the port 12000 must be opened and forwarded.
The ip adress for andlinux ist 192.168.11.150. CCcam.x86 must be in var/bin, the same for run_debug and run_background. The cfg file and the other config file in var/etc. In DVB viewer please use not the newest softcsa, this version makes problems and use not the emubox pre beta 0.2.
