do i need a dvd burner to back-up dvd games?

[ive_seen_my_fate]

Thanks 4 your help but, if i was backing up tony hawks3 which files do i need to keep?

the files on the disk are:

50400
demo
iop
movies
music
streams
skate3.hed
skate3.wad
sles 504.35
system

if i remove the movies and music, does this mean i will not have sound on the game, i assume the movies are just the FMV between levels right?

OH yeah! if i back up the game i cannot use clone cd if i need to remove files, so what program do i need to use?
