Section 3. Using Your PlexCombo
Playing CDs and DVDs
To play a CD or a digital video disc, insert the disc with the label up (for CDs). The
PlexCombo plays both single-layer and dual-layer DVDs.
DVDs, the first time: A code on some DVDs allows them to be played only in a
certain regional area, such as North America, Europe, etc. When the drive ships there
is no region code set. The first time a DVD that has a region setting is inserted into
the PlexCombo drive, the act of inserting the DVD sets the drive to that region code.
If you later insert a DVD with a different region code, you are prompted to either
accept changing the region code or not. If you don't accept the change, then that
DVD will not play. If you do accept the change, then the PlexCombo's region code
setting is changed. But remember: you can change the PlexCombo drive's region
code only 5 times. After that, you can't change it any more.
Advantages of Buffer Underrun Proof Technology
The PlexCombo 8/8/24-8U incorporates Buffer Underrun Proof technology, which
guarantees that you can write discs at high speed and still use your computer for
other tasks while you're writing.
To prevent the interruption of data during writing, every CD-R/RW drive has a
buffer, a memory chip that acts as a kind of "holding area." (Typically, the buffer
size is 2 MB or 4 MB.) However, this buffer can be emptied quickly when you write
at high speeds, or if you use other applications (like surfing the Internet or playing
games or watching movies) while writing.
Buffer Underrun Proof technology compensates for any interruption in data flow to
the disc. It "remembers" where writing stopped on the disc when the data flow was
interrupted, then restarts writing in the same place once the data is available again.
Buffer Underrun Proof technology in your PlexCombo 8/8/24-8U means you can
safely use your computer for other things while you're writing to a CD-R or CD-RW
disc. It lets you multitask freely and easily, and lets you successfully create CDs on
the first attempt.
