CD & DVD work in practically the same manner. Both store data as a series of reflective marks on the surface of the disc. The thin plastic or metal foil layer of the disc gets hit by the laser beam of the writing drive. The laser energy thus produced creates tiny bumps in a spiral pattern similar to that of a long-playing album.

Here, by downloading means that you want to write it on a DVD and later read from it. Moreover, The DVD is RW which means re-writable. In normal DVD's, data once written cannot be removed but in case of DVD-RW, data can written and removed as well.. For writing a DVD there is no special software... Windows Xp, Vista and 7 have preloaded windows applications that can write the data. But if you want more organisation like you want to add effects, and stuffs like that than you can use Nero. Otherwise, as I have already said, for simple writing no SPECIAL software is required.

What two characteristic give a DVD more storage capacity than a CD?
The DVD uses a red laser with a smaller wavelength, not the long wavelength red laser that is used for CDs. The shorter wavelength allows the beam to be more accurate. This accuracy means that more data can be stored on a DVD than a CD. Data can only be written on one side of a CD, but a DVD can be written on both sides depending on the type of DVD (for example, DVD-5) you have. For more information see the link below.
