hi, i have a pal dvd that neuron2 at doom9 has determined is blended fields. i want to convert it to ntsc (i have already w/xesdeeni's script) using dgpulldown that fulcilives let us know about. so i'm looking at tips to script my avs. so far here's what i've been told:

-its a commercial pal dvd, but apparantly was converted from a ntsc source and they used blended fields.

-i was told at doom9 that i need to find out if this soure originally was
NTSC FILM with 23.976 fps
or
NTSC progressive with 29.97 fps
but it is in pal format how do i do that?

thanks
