i have tried google on this subject and there is not much help. it just added to my confusion. from what dark jedi said the encoder must add the flag. or am i lost and it is the dvd author that adds the flag? as i understand it a flag and a template are 2 different things. so i have trouble finding any flag settings in vegas or dvd architect. i see 16:9 templates but that just gives me 3:2 in16:9. so what i need to know is which program adds the flags and where are these flag settings? i am going back to poke around in vegas now to try and figure it out but i have not seen those flag settings yet.
