Multi-angle
With regular TV programs, although multiple

scenes, only images from one camera at a
time are transmitted to your TV. Some DVDs
feature scenes shot from multiple angles, let-
ting you choose your viewing angle as desired.
Multi-audio (Multilingual dialog)
Some videos feature dialog recorded in multi-
ple languages or audio recorded in multiple
tracks. For example, dialog in up to 8 lan-
guages can be recorded on a single DVD-Vi-
deo, letting you choose the language as
desired.
Multi-session
Multi-session is a recording method that al-
lows additional data to be recorded later.
When recording data on a CD-ROM, CD-R or
CD-RW, etc., all data from beginning to end is
treated as a single unit or session. Multi-ses-
sion is a method of recording more than 2 ses-
sions in one disc.
Multi-subtitle
For example, subtitles in up to 32 languages
can be recorded on a single DVD-Video, letting
