•If your VCR (or other external devices) has an S-Video terminal, S-Video connection is recommended because S-Video signal has the better quality than VIDEO signal of A/V IN..

•If your external device has Component terminal and S-Video terminal both, Component connection is recommended. Component video signal is superior to S-Video signal.

•The sound or image signals coming into COMPONENT or S-VIDEO will not be transmitted to MONITOR OUT terminals.

•S-VIDEO and VIDEO in AV IN share the same jack with AUDIO input. Thus ,they can't be used at the same time.

•COMPONENT inputs accept only 480i video signal, so make the external equipment(DVD or DTV Set -Top Box) to 480i mode.
