I've been using TMPGEnc DVD Author but since there was a need to make multiple langurages in the DVD, I have to switch to DVD Composer. There is one thing I normally do in TMPGEnc but have not figured it out in DVD Composer. I have all me video files converted to mpg files and I would put all the mpg files in one Title of the DVD. In DVD Composer, it only allow me to put one mpg file per Title, or they call it Track. I would need to add another Track if I need to add another mpg file. The reason I want them all in one title or track is when play back the DVD, I can use the >> buttone on the remote to easily jump from one chapter to another where each chapter is one of my mpg files. With DVD Composer, each of my mpg files is in one Title and the >> button does not work between Title.
