I've been searching,reading for awhile and cannot find an answer. Does anyone know how to add the 3d flag/tag so your device knows it is 3d content? Youtube 3d adds a tag and the device knows it is 3d, my videos recorded from evo3d, knows its 3d. If i encode or download a sbs 3d file my phone doesnt recognize it and I have to manually select 3d option,which is fine,except that it doesnt support over under this way. But if I download a over/under from yt3d it plays fine on its own. I've looked at various files with mediainfo and gspot, and really dont see anything to help me out. thanks for any help.
