A DVD contains a number of video files which you need to copy from the DVD before you can convert them.

Here's how to find the movie files on a DVD:

  1. Insert the DVD into your Mac
  2. Right click on the DVD and select Open
  3. This should open the Finder.  You will see two folders: AUDIO_TS and VIDEO_TS
  4. Open the VIDEO_TS folder
  5. You will see a bunch of files but the ones you want the the VOB files.
  6. Copy the VOB files to your Mac (the Desktop is a good option)
  7. Drag the required VOB files into Smart Converter Pro and convert as required

NOTE: the VOB files are just named sequentially on a DVD.  You will need to use trial and error to find the video that you are looking for.

If you see a message saying VOB conversions have been disable read more here.
