I have authored a DVD of a movie using GUI for dvdauthor, and burned it to disk using Image Burn. My front page is a still image with two buttons - Play (which plays the movie) and Chapter Menu (which goes to a next level menu to select chapter points). The disk works with no problem in a computer but when I put it into a domestic dvd player (Sony NS-36) the front page comes up with neither button highlighted, so I can't use any navigation tools to make a selection. Any other disk I've tried in this player, including ones I've made myself, plays ok. The question is (and apologies if this is not the best forum) is the problem likely to be with the authoring software, the burning software, the DVD player or the disk itself, and are there any steps I should take to prevent this happening? Grateful for any suggestions.
