FAST DUBBING
DUBBING MEANS A COPYING FUNCTION BETWEEN HDD TO DVD DISCS.
COPYING BETWEEN HDD TO DVD IS A COMPLETELY DIGITAL PROCESS AND THEREFORE INVOLVES
NO LOSS OF QUALITY IN THE AUDIO OR VIDEO. SO THIS MEANS THAT COPYING CAN BE CARRIED OUT
AT THE MAXIMUM SPEED POSSIBLE.
<< DUBBING SPEED RATE >>
NORMAL DUBBING : SPEED RATE MAX X1
FAST DUBBING : SPEED RATE MAX X4
WHEN FAST DUBBING FROM HDD TO DVD, THE SPEED OF COPYING DEPENDS ON THE RECODING
MODE AND THE KIND OF USING THE DVD DISC, AND THIS MODE IS NOT AVAILABLE FOR EDITED VIDEO
TITLE IN HDD.
WHEN FAST DUBBING FROM DVD TO HDD, ONLY AVAILABLE WHEN COPYING VR MODE DISC(DVD-RW)
TO HDD, AND ONLY NORMAL DUBBING AVAILABLE WHEN COPYING VIDEO MODE DISC(DVD+RW/RW,
