It depends on what exactly you want to do. The options are:
(1) Copy as .iso file (image). Use Windows Explorer to organize the images. Mount them before playing.
(2) Rip CD's into individual tracks. Organize those CD's and tracks using the library functions of your favorite media player.
(3) Same for DVD's as for CD's, more or less, although you don't rip into "tracks". But there are player program that can play the ripped data.
