hello, demodulator is a perfection, a picture on top, fast channel change, easy to use for the initiated perfect bistros despite 57% antenna bistros Max (location problem) even during a storm with torrential rain, to summarize, a perfect, thank you and thank you amazon aston without whom I would not have taken demodulator is when I think of that I would have missed if I have a stomach ache. here is one week now that I use my aston xena twin 3d hd ready, if it were written the highlight of the demo is the weak point here, for the time shift most of demo allows to instantly record the program or other but not out of step with Xena, very unfortunate, the update software from the satellite does not work, I made several try leaving the 2:00 each time and nothing happens, it is written upgrade but nothing goes by, more by the time he informed me that PLUSIEUR chain are no longer accessible and each time I have to put it out completely with the on / off button has the arriere.voila for now, I expect new surprises with duration of use.
