NTL/Telewest have upgraded their network.... boxes are being knocked off all over the place. This applies to pace/samsung/dbox/eurovox/fta101.
I dont know of a software update for the eurovox that will fix your box at the moment. I'm working on an FTA101 trying to get that up and running again and after I've done that I'll move on to the eurovox.
But no promises.
Doesnt seem like there is a direct fix at the moment; I'm not familiar with eurovox unfortunately.
