Finally been getting around to ripping some shows I’ve collected and had forgotten some included artwork in the extras. However outside of screenshotting each art piece I’m not sure how else to rip/extract them.
They’re shown as still images in a simple gallery with previous, extras (to return to the extras menu), and next buttons beneath the image being viewed.
Try MakeMKV to extract the entire DVD first, then use VLC to open the extracted files and use its snapshot feature (hotkey is usually Shift+S) to grab the artwork as you browse thru the gallery.
