I want to create a video dvd ( no menus, just "plug and play" ) from a few video files. I`m doing it like this: ffmpeg -i sample-media/hellboy-2.wmv -y -target ntsc-dvd sample-media-to-mpeg/hellboy-2.vob dvdauthor -o sample-dvd -x dvdauthor-settings.xml mkisofs -dvd-video -o hellboy-2-trailers.iso sample-dvd/ where "dvdauthor-settings.xml" is: link. But when I try to play the iso file in windows it says: Windows Media Player cannot play the DVD because the disc prohibits playback in your region of the world. You must obtain a disc that is intended for your geographic region. When I open the *.IFO file with IfoEdit it says that all world regions are unabled. Can someone tell me why is this happening? ( maybe the whole process of creating the *.iso file is wrong? )
