So what do you think is the problem? must be image or drivers, because dvb stick works in pc, also works in vu+ but just first time you boot the device, after be running a while it fails, and it fails in several devices, solo, uno and duo...If you tune a channel and you see another channel ... seems there are some settings problems and the DVB USB device is not your first problem.
I am going to test right now avermedia volar green, the vissionet works perfect..
