Hi Fusca,
I see you have found the solution:
You have to plug the NTR83 to a TV FIRST of all to execute the configuration wizard.
Each time you will do an update of the firmware you will have to do that.
I recommend you to update to version 1.54.
If you have any problem to order your your DVB channels don't hesitate to ask.
There is a way to do it with Telnet and a little program.
I did it today and now all is fine.
regards !!
