Yamaha DSP -A780 - Manual (Page 29)

NOTE: Adjusting the MASTER VOLUME, BASS, TREBLE controls,
etc., or selecting a sound field program has no effect on the material
being recorded.
NOTE: Composite video and S video signals pass independently
through this unit’s video circuits. Therefore, when recording or
dubbing video signals between two video cassette recorders, if your
source VCR is connected to provide only S video (or only composite
video) signals, you can record only a S video (or only a composite
video) signal on your second VCR.
NOTE: Please check the copyright laws in your country to record
from records, compact discs, radio, etc. Recording of copyright
material may infringe copyright laws.
If you watch a video software that uses scramble or
encoded signals to prevent it from being dubbed, there may
be a case that display information superimposed on the
picture and/or the picture itself is disturbed according to the
type of the signals.
