A lame question need answer plz

:confused: undefinedundefined
my question is can i burn dvd movies or dvd data onto a dvd using cd writer?which software should i use?
i am asking this question b’coz i came across a site saying that i can copy dvd to dvd without using dvd burner.plz help me in this topic :confused:

this kind of tool let you think you can backup your movie but the format is different… either it will be vcd or svcd or divx… so … it is not the same quality nor compatibility … the dvd burner price dropped a lot… please consider this investiment.
