I have a home-made DVD that someone put together, and it has a strange problem. When I play the main movie, it plays as if it were a menu, not a video title. If I play it on my stand-alone player, instead of showing the timecode, it just says "Menu". Playing it in Windows Media Player, the "progress bar" along the bottom never advances, and I can't fast forward or rewind. More telling, when I play it with Zoom Player (my media player of choice), instead of showing the progress of the video, it just says "Menu". However, this video title shows up in DVDReMakePro as PGC 1 under "Program Chains", and is not under "Menus en".

I've tried using the "Enable all operations" function, but that didn't fix it. Is there some flag that tells the player that the title is a menu that I am missing? If so, how do I fix it?
