Hola Alejandro!!!

If the dvd is R4 (I assume that, this is the standar here) in the 99.99% of
the case  you must set  -ofps 23.976; you  can know if  you need it  or not
encoding four  or five minutes  of the movie  and comparing the  numbers of
skip/drop frames; you must choice the  option that give you the less number
of them.

Saludos,

Martín
