I have had both boxes and can say that my experience is that the duo is far far better. i had the uno for three hard weeks and it was a constant problem, problems with the hdd , problems with scanning channlels, problems with crashing, problems with hdmi.
Everytime i turned the box and tv off when i wanted to get it back on again i had to go behind the tv and pull the hdmi cable in then out.
So after three weeks of frustration i decided enough was enough i took it back and insisted i have a duo.
Now everything that wasnt working does work.its much much better.this is only my experience mind and some people im sure will have unos with no problems,its a bit like mobile phones some are ok some have software problems.it s all down to luck, but id rather not deal with luck and deal with a item that works when it feels like it.Unos should be recalled. vuplus know this but are too greedy to accept the facts.
As for the drivers and firmware upgrade i also tryed doing that and got crashes so just no answer for my problem.
on the bright side i now belive i have the best box in the duo and wouldnt change it for anything. good luck to evryone,if i can help or advise please give me a shout........
