I have a couple of Dual Layer DVDs that have multiple titles on them and was wondering if there was a way to: 1) Edit the Main Menu in the VIDEO_TS folder to remove the other titles and 2) Separate these into multiple DVDs each with its own Menu and Chapters? As an Example, I have recorded a TV show and want now to go back and give each episode it's own disc, what is the best way to do this? Any help would be appreciated.
