Computer dvd burner

i am buying a Single Drive: 16X CD/DVD burner (DVD+/-RW) w/double layer write capability. could some1 help me to understand what exactly that would allow to do as pertaining to dvd burning?

In general, you would be able to burn all dvd formats except DVD-RAM.

Are you interested in buring Video? If so, make sure you get a drive that can bitset +R and +R DL disks to DVD-ROM in order to increase compatablity of stand alone dvd players.

No matter what burner you get, try to use quality media. For single layer + and - R’s, most people recommend using verbatim or taiyo yuden made blanks. For DL burning, use only verbatim.

so do i need some sort of software?

Yes, what you will need will depend on what you are going to be doingg, copying, converting, authoring etc.

…and buying the sources (movies) in the first place.
