I'm sorry, but I still don't understand ... what does the ATV have to do with it and what about the VIX ? What settings ? I do not understand. Did you move the configuration from VIX to ATV ? Or what ? Hmm...
Does your terminal connection (SSH or Telnet) work ? It will help a lot if you write that yes or no. The problem can be further diagnosed via Shell. You can also try reinstalling OpenWebif from the Enigma feed + restarting Enigma.
