It starts normally and I can reboot many times. However there are no channels...

Update: I unpluged the tuner and the problem stops. However as you understand the box cannot function without a tuner...

dm 800 pvr:
GUI (enigma2):
Firmware (Release from 11.05.2008) :

I yesterday bought a DM 800. I configured the main settings and then I tried to restart. The dreambox rebooted and got stuck while rebooting. The oled screen kept going from the half of the progress bar until the end, then turn off and then turn on and do the same again. An endless loop! If I power down the DM 800 for about 30 minutes it will then boot again normally. If I restart, the same problem again and again. Please help.
