Burning DVDs (Geek-speak for taking a movie from your PC's hard-drive and making a copy onto a DVD+R) is good for making a backup of your movie that can be watched on any DVD player.

[edit] Steps

Download IFOedit, a free program which manipulates the IFO files found on a DVD, that we are going to use to make new IFOs.
Extract the contents of IFOeditxx.zip to an accessible folder.
Run The IFOedit.exe program from the folder and click the button labeled "Create IFOs".
Use the next window to select the first VOB file that you have on your hard drive and click OK to begin the new IFO creation.
You should now have a complete and perfect copy of the DVD with new IFO files on your hard drive, which you can burn to a DVD-R at your leisure.
Alternately, just open DVD shrink, and select "Open Files" at the top. Deselect whatever languages you don't want, and then click "Backup". Choose where to store your temporary files, and click "OK" it will now shrink it and then burn it!
