Help!! I'm sure there are loads of you that do what we want to. Downoad free movies from Amazon Prime to your tablet, in this case a Fire 10 hd, then mirror them on the van tv and watch in comfort. We have tried connecting to the tv (Avtex) with usb lead and the tv seems to want to cooperate as the correct screen comes up which tells us it cannot find the device. What are we doing wrong or is it another one of Amazons litle tricks to thwart you. Thanks.
