For DVD players that can't do Subs/Tracks, does this mean they can't recognize Menue's and Chapters. What if I use Ulead Movie Factory to add Menues and Chapters to a VCD. Would a DVD player that can't do Subs/Tracks just not play the VCD at all? Or would it just not show the menues and play the VCD just fine????

For instance the Sony DVP-CX 850D in the DVD Players section (of thi site) says it can't do Subs & Tracks. When would VCDs not work for these DVD player limitations??
