The product by itself serves its purpose and effectively to transfer their VHS to DVD ... Except that the tutorial does not explain how to use various functions, it only summarizes its characteristics ... Except he must lose a lot of time on the net to understand that only copies of ntsc..alors pal or ntsc that I have and never will copy in black and white ... Except that claims the product key for installation which is obviously neither in the box or on the packaging or on the key ... Unless it works very poorly on windows 7 which is not mentioned anywhere part..Sauf your services say they do not know the product and can not find out about all these problems ... BRAVO TO YOU AND THANK YOU
