Blinking buttons got an acard 3-1 copy box the third dvd light stays green and wont copy have to take the disk out for the other 2 to work ?

SOURCE: acard 1 to 3 duplicator can't seemto get past the traget disc not ready

of course theres a problem but what are you doing with the thing? are you formaating the disk first to render the dvds in the target drives? are you using the right DVD like DVD+ DVD+- or Blueray? need more information to help you. and it the DVD you are copying has been redered on another machine it won't copy it anyway. You have to use the same machine to copy it as thats how they protect copy rights now days.
