New DVD Drive need advice

I`m currently in the market to buy my first DVD Drive and i have some questions.
i know there are many good drives out there but im not sure what would best suit my needs. im looking for something that i can backup movies/games and music. i have a cd-rw drive but i dont know if ill still need this for certain things of if there is a dvd drive that can do it all.

i dont really know the difference between the many standards in dvd such as dvd+rw, dvd-rw, dvd-ram and such. is one better than another or do i even need to get into that stuff?

im just looking for a good drive that will not cost an arm and a leg and not be a coaster factory either. something that will make reliable backups of copy protected cds and dvd games and movies.

thanks in advance
