Here's a little step-by-step to get you going:
Create a new folder for your movie files, and decrypt all of the original DVD's files using either Smartripper or DVD Decryptor (set to File mode).
Create a blank folder for the DVD2ONE project.
Open DVD2ONE, and select your original file as your source. Select the blank file you've just created as your destination.
If you set it for "full disk," it'll copy absolutely everything that the original had on it -- reducing the file size down to 4.36Gigs. You'll likely lose quite a little bit of the movie's overall picture quality that way, so if the picture quality really matters to you, I'd go with "movie only." If you go with the "movie only" route, then you'll next see a screen which asks you what you want to keep. After chosing everything you want, start 'er up, and grab a bite to eat. Within 15 minutes to a half hour later, you'll have a file of your movie that's ready to burn.
As far as burning it goes, there's many options you can go with. If you currently HAVE no burning program (which you'll need) that supports DVD-compliant streams, then I'd suggest the newest Nero (a quick search on your browser will lead you to their website, which should direct you as to where to get it). I've also used B's Recorder Gold successfully for the same purpose. Whatever you decide to go with, make sure it has the following:
"Disk-at-once" recording abilty (many set top players can't read a disk recorded at "track at once").
Nero has a "Video DVD" option that searches for DVD-compliant files (which you've just created with DVD2ONE), but at least make sure that the program has a "Data DVD" option, which will let you burn your entire file (which you'll have to re-name as "VIDEO_TS").
I'm sure this post will get riddled by suggestions as to how to burn a movie, and which burning program is better than this one or that one (everyone's got their favorites -- mine's Nero), but the point is to check into what's out there, since all have certain functions that others don't. Also remember that re-writeable DVDs are your best friends whenever you're not sure.
Hope that gives you something to go on!
