My parents had all the family slides scanned by a photo lab. The lab returned the digital photos on two DVDs as movies; there's some stock music over a slideshow with fades between each photo. The discs contain only a handful of files, including some very large VOB files. I'd like to extract these photos and import them into iPhoto. I saw this answer about capturing stills, and that might work if I can figure out the right offset from the beginning and the right capture rate. But this approach seems very error-prone for this purpose. Is there a better way? I wish the individual photo files were stored in a directory on the discs, but they're not there.
