I had a VU+DUO and I changed for an AMIKO ALIEN2 because this
kind of receiver FULAN ( for me ) is the future. Most of people
does not know the potentialities of them. It is very difficult
to flah but you have almost everything with it. 3 Tuners, 2 sat
and 1 Hybrid (cabe / TDT ) 540Mhz memory ( VU+DUO has 128 Mhz )
711 RAM ( VU+DUO has 384 ) With some images you must have a pen
to make a SWAP for the memory. It is too low. Here, the VU+DUO
no sell anymore. In 1, 2 or 3 months you have the VU+DUO2
So, to choice I say BUY the DM7020. ( Or the AMIKO ALIEN2 if
you want to spend time to understand this FULAN model box ).
Good luck
