How can Ты get the clips to make videos? And can Ты download them from a DVD?

I remember asking this already (but only one person answered, and she's not here anymore)

I want to make a Youtube video, but I don't know how to get the clips. :/

Oh, and can Ты download Видео from the DVD? (Mom will be SO angry if I buy it. XD)

(I know I already made a Youtube video, but I can't use it anymore because a family member сказал(-а) it's the reason my laptop got a virus. HE STILL DOESN'T HAVE PROOF!)
