In the Menu Inspectors General tab, try adjusting the Start time.
You can also put butons over video tracks by using the subtitle features ... that is explained in our DVDSP 101 tutorial:
If I adjust the Start time then menu will start playing from that point but I would like to run my video first and then to bring my text buttons. I was not able to do that yet in a single menu. I have read about the subtitle features but it said that it only will show one subtitle at a time but I will give it a try. I have ordered DVDSP from you so I 'll check it out when it gets here. Thanks for your advice anyway.
