[dvd::rip] ripping a DVD-Video to burn another DVD-Video

[Ricardo <f4k3n322@xxxxxxxxx>]

Hey there list!

I know this is kind of silly, but I just don't what to do if I want to only copy the entirely dvd-video and them burn it as an dvd-video. untill now, i can rip the disk without any error, except for transcoding saying it needs +/-20gb for the entirely process, but as i dont want to  "backup it" and dont want to burn a SVCD, but a copy of this disk, i just skipped this steps. 

after all, tried mkisofs with -dvd-video options, but it failed. 

so... what should I do?

cheers! and thanks!

ps.:
to ilustrate... 

i want to do what i used to with cd-audios. put it on the drive, rip it to non-compressed format, burn it as cd-audio - a simple copy without having 2 drives (my case).
