Firstly download Blackhole and put it on the usb stick and then put a proper bit of software on your Vu+ Duo :-righton
I could never get on with VIX, i didn't like the look or feel of it. I also found it unreliable on my box after only 24hrs of testing. The emus wouldn't stay up for more than 12 hours no matter what i did and it green screened more than a few times
I put the lastest blackhole back on it and the emus are still running 6 days after i left it .
I also think Blackhole looks better than VIX and has more nice toys available for it
I find Blackhole ultra reliable and a lot easier to use than VIX
