About DVD software types and the conversion method
DVD software can be divided into two types: film-based software and video based software.
Video-based software is derived from TV, such as dramas and sit-coms, and displays images at
30 frames/60 fields per second. Film-based software is derived from film and displays images
at 24 frames per second. Some DVD software contains both video and film.
In order for these images to appear natural on your screen when output in progressive format,
the progressive signals need to be converted to match the type of DVD software that you are
watching.
Note
When you play video-based software in progressive signal format, sections of some types of images may
appear unnatural due to the conversion process when output through the COMPONENT VIDEO OUT jacks.
Images from the S VIDEO OUT and LINE OUT (VIDEO) jacks are unaffected as they are output in the
normal (interlace) format.
