• DVD+R, DVD+RW, DVD-R, DVD-RW, CD-R, or CD-RW discs
formatted with packet writing software such as “DirectCD” (including
commercially available preformatted discs) cannot be read in this drive.
• The use of Sony DVD+R, DVD+RW, DVD-R, DVD-RW, CD-R, or
CD-RW discs is recommended.
Precautions for using “Click to DVD”
• Close any other software (including software running in the background)
before using “Click to DVD” and “Drag’n Drop CD+DVD” to write
data.
• You should have at least 256 MB of RAM in your notebook when using
“Click to DVD” to write data. For details on expanding memory, refer to
the manuals provided with your notebook.
• To write data using “Click to DVD”, log on as a user with computer
administrator privileges.
• When writing data to DVD+R, DVD+RW, DVD-R, or DVD-RW discs,
the discs are written using the “Disc-at-once” function. Therefore, it is
not possible to add data to the disc later. For DVD+RW or DVD-RW
discs, you can rewrite the disc once you have deleted all the data on it.
• Writing to DVD+R, DVD+RW, DVD-R, or DVD-RW discs can vary
from a few hours to several dozen hours. The actual writing time depends
on the notebook model and the length of the source material.
• Because data is temporarily stored on your notebook’s hard disk when
using “Click to DVD Automatic Mode” to create a DVD video, there
must be enough free space on the hard disk. The values below are a
general guide for the amount of hard disk space used to create a DVD
video for different video recording lengths. Further, the video bit rate is
automatically adjusted according to the length of the recording.
Length of recording Hard disk space used Bit rate
30 minutes 6 GB 9 Mbps
60 minutes 10 GB 8 Mbps
80 minutes 10 GB 6 Mbps
120 minutes 10 GB 4 Mbps
