I have an older camcorder (Hitachi DZ-MV730A) and a lots of DVD-R discs. I want to convert them so that they can be played on both a computer and a TV. How can I tell if a disc has already been finalized (using the Camcorder), and how can I convert it to digital that is shareable and playable on both laptop and TV? I have already converted all my other formats, either on my own or through Legacy Box, but no services convert DVD-R (mini) discs. I have a MacBook Pro (2015 with Retina) that has Parallels with Windows 10. Thank you Hope you are all well.
