Hi! I have a commercial DVD ripped with the 'Mac the Ripper' and since I got that DVD in Japan, I want to add an English Subtitle file to the DVD and burn it to DVD DL (full quality DVD playable on DVD players). I have a subtitle file *.sub and I have been browsing internet how to do that on OSX. Could someone please teach me how to do that? I am a beginner on Mac OSX by the way. Thanks very much for advance
