I purchased sometime ago a TERRATEC T-Stick to use with SDR software to (mainly) receive aircraft broadcasts on 126MHz in my local area. It also works nicely up around 1GHz to receive aircraft ADSB signals - so the frequency coverage is not a problem & the PC otherwise works nicely with the T-stick. (I live in Queendland about 200 miles west of Brisbane, Queensland. In a nutshell, the DVB-T works just fine - but recently tried to receive & watch digital free-to-air TV using "DVBViewer TERRATEC Edition" software, which is supposedly the ducks nuts for this particular receiver. My PC is a Z5610 "All-in-one" running Win7 64 bit. 8Gb RAM The DVBViewer program does not recognise the presence of the T-stick. It seems to be mainly a software problem, in that the designed software just doesn't recognise the DVB dongle is connected, where as the PC definately knows its there. A couple of SDR programs like SDR#,HDSRD,RTL1090 and ADSB-Scope are perfectly ok. I have tried the DVB stick & software with a laptop running Vista 32bit with the same no-go as far as watching free to air TV is concerned. So .. what gives? Would appreciate some help Gavon
