I flashed on openVix , on my second tiviar alpha , my dvb t tuner is still goosed though , at this point I think the tuner is just broken , I swapped in the one from living room to test and it was fine, so the signal is fine and the settings on the box are all correct , it just stopped working all of a sudden.
Therfefore I think it's a dead duck , shame as the satellite tuners and box itself are grand other than that tuner which I used for saorview.
