Verbatim dual layer discs play fine but won't Start automatically after hitting play on the menu

Hi, I amnew to DVD burning. I just got a dvd burner TSST Corp Samsung. I have been using Verbatim DVD +R DL discs for long movies and DVD+ R Sonys for shorter films. I am using DVD Fab HD decrypter to rip, dvd shrink to make an .iso, and imgburn to burn the movies. My question is why on the Dual layers I burn does the dvd stop completely after pressing play in the menu? The movie itself will play perfect, but it just wont start after hitting play on the menu. Also when I hit forward on my dvd player, it won't go. I have to go to the second chapter and press back until the opening credits to start the movie from the beginning. It only does this on dual layer disks (the verbatims I have). Is there a way to keep this from happening?

The Dvd Starts fine after hitting play on the menu while playing it on my computer, but not in my pioneer DVD player. I changed the book type to dvd rom as well, and it still will not start up on my stand-alone dvd player.

 

anyone?
