I only have v8 but it should be similar in 9, click on make movie, select disk, then there should be a tab for settings, in there is an option to creat disk content but not to burn to disk, just select a location on a hard drive where you want the files to go.
Then you can use nero, or record now, ulead etc etc to burn your disk with the dvd files.
DVD shrink needs the files in the first place, which WindSpirit doesn't have at the moment.
