I used TMPGENC DVD Author 3 With Divx Authoring. However, when I went to play the DivX in my Philips DVD player that DOES play DivX, I can't get the menu. It only has the root folder, and the video file itself, and not only does it not play the custom menu I have, my chapters are gone. Any advice?
If your player isn't DivX Ultra certified, then it won't playback menus. Same goes for chapters. So the advice (once you have verified that your player isn't Ultra certified) would be to buy a new player or give up on the features.
