While still relatively new to dvd copying, I've successfully copied a number of dvd's. Well, I guess "successfully" is questionable, because I'm getting mixed results with respect to closed captions. Some of my copies have them, and some don't. At first I thought that the problem was something like capturing video from vhs, but then I realized that shouldn't be it: if the closed captions are digitally encoded on the original dvd, copying the dvd should copy the digital data used for closed captions. Are there any known circumstances where copying a dvd would result in the loss of closed captions? Say any kind of "shrink" operation, or burning from a video_ts folder rather than an ISO? Or, would the ripper settings (I use dvd decrypter) come into play here?
