In the past, we had no much choice but used to use Nero to make iso image from one dvd and burn it to another dvd disk. However, nowadays, we have plenty of choices. The most impressive one is ImgBurn freeware.

Although it is small in term of size, ImgBurn has everything we need to copy one dvd to the other.  ImgBurn is the most powerful burning application I can find, for no other software comes close to its advanced features and options.

ImgBurn includes support for:
