miraclebox twin hd two dvc tuners can't record one channel and watch another

[john doe]

have you setup A & B exactly the same? make sure that you are not recording two channels at once. if you record (one channel), try pressing up arrow and see which channels you can watch and the ones that are not, which will look darker. when you are recording two channels, there is some channels you can watch and most one cant. if you get this, then re=setup your tuners and scan again
