Very tiny and great application for converting from DVD9 to DVD5 is DVD Shrink, this is my personal favorite. It doesn’t always help you to achieve the best quality, but it is the fastest method mdash; that’s for sure!
After opening DVD Shrink click on Open Files (if you have DVD content on your hard drive, choose VIDEO_TS folder) or Open Disc (if you have DVD disc inserted in your drive).
Then press Backup! In Target Device choose where you want DVD Shrink to save your backup. But the most important is Quality Settings → i would recommend you to check both check boxes and choose Sharp (default).
That’s it just it – DVD Shrink will do the job in two passes!
