As promised, here is the first release of DVD Cover Art Finder (version 188.8.131.52), along with the source code. Read on for download links and a usage tutorial.
This usage tutorial begins with the DVD already properly ripped to the hard drive. I’ll have to make a tutorial about how to do that later, but for now you could use the tutorial that I used to learn how to do that. (link)
Next, click “Scan for DVDs”.
Select the folder where you store all of your DVDs and click OK.
Be patient, and DVD Cover Art Finder will show cover art, which is currently picked from Amazon.com. If the right cover art doesn’t show up, edit the Title text box and click the “(re)load coverart” button.
Click the “Save” button. This will save the cover art to the DVD’s folder, as well as rename the DVD’s folder to match the title. Saving also creates a data file to keep track of the information and places that in the DVD’s folder.
