DVDLab Pro V1.0 problem

I’m having trouble with DVDLab Pro v1.0. I can compile a Movie ok, it plays ok on PowerDVD, but will not play on standalone DVD player. If I use TMPGenc DVD Author v1.6, The DVD will play perfect on all players. Is there a function which I need to enable/disable in DVDLab Pro so I can make it play on standalone DVD players.
