I am producing a series of DVDs in Pinnacle with lectures on at the mo, but made a big mistake on the last DVD I produced. I got the course title wrong in the DVD menu

, so all the DVDs I have copied from the master are useless. The problem is that I deleted the original files on my hard drive so I can't go back and have pinnacle recompile another master with the correct title on. So I wonder whether it would be possible to rip the master back to my drive and then import this back into Pinnacle as a movie file. I could then cut off the title sequence and add a corrected menu. Any thoughts? I've got Nero but this doesn't cover DVD ripping. So any ideas about a DVD ripper?
Thanks in advance for your ideas!
