Locking up using full clone function

the copy titles works great, never have any problems, but 99% of the time the clone full dvd doesn’t work. would really like to have this work, especially to get english subtitles for watching movies with sound quiet. any advice?

Are you using elby CloneDVD2? Which version? Could you elaborate on “the clone full dvd doesn’t work”? What happens?

yes, version when i go into program i have 3 choices on the right. top one is copy dvd titles, middle one is clone dvd. bottom one is write existing data. the middle one that should make a full clone with all menus and extra stuff is the one i have trouble with. it will go most of the way and then lock up. locks my computer hard. have to shut it down.
