Recover data from an old DVD
I am a radio producer and have many years worth of shows backed up as data on DVD. One that I now need does not mount or even show up in the Finder. I have a USB DVD player/recorder that works fine otherwise and another similar disc from the same era works fine. I'm guessing that there must be an issue with the old DVD disc itself and I'm wondering if there's any way to look at and/or recover the data that's on it.
