scrambled dvd files..!!!

Hi guys,

Last day I copied a dvd movie to my hdd...but now when I'm playing it, the whole thing looks scrambled..there was no problem while viewing it from the dvd. Now I wish to burn these files (probably after converting to divx) and I want to view it in the original quality. What should I do..?? Please help me.Thanking You.

regards
