THE MACHINE WORKED PERFECTLY--HOWEVER MY COMPUTER WAS NOT UP TO IT...NOT ENOUGH RAM TO RUN IT CORRECTLY- I WAS VERY IMPRESSED WITH THE UTILITY OF THE SOFT WARE, HOWEVER AND WILL MAKE USE OF THIS UNIT IN MY NEW MACHINE--UNFORTUNATELY I NOW HAVE A COMPUTER THAT HAS THIS TYPE OF EQUIPMENT BUILT IN, SO NOW I HAVE TWO DVD BURNER TYPES--I AM GOING TO TRY THE MACHINE I BOUGHT FROM YOU IN MY NEW MACHINE--I THINK IT WILL BE A GOOD ADDITION .
