DVD Burning Question

Hi all, I am using IMtoo dvd burining software to burn my .avi file straight to dvd, After the burning is complete and i play it on a dvd player its out of sync by about 1-2 seconds.

Is there something i’m missing to do? Or do i need to use a different program, I just don’t understand why it plays ok on the computer but then when placed on disc it goes out of sync.

I’ll appriciate any help, thank you.
