9 NTSC Closed Caption

The Nugget supports closed caption on extended NTSC video files encoded as 512x720. When
such a file is loaded, you can adjust the VBI using DoremiAM to move the video so the closed
caption data in the file will align with video line 21. For files that are properly encoded the closed
caption will be aligned with video line 21 when VBI is set to +3, which is the default value. If your
file is not properly aligned, you can change the VBI value until the closed caption data aligns
with video line 21.
