About Disc
Q:
Can I play DVD videos or video CDs I
purchased in foreign countries?
A:
If the region number (local number) includes
"ALL" or "3", and the video format is NTSC,
you can play DVD videos. About video CDs,
if the video format is NTSC or PAL, you can
do it.
Check the cover of your disc.
Q:
Is it possible to play a DVD video without a
region number (local number)?
A:
Discs with region numbers (local numbers)
show that they meet standard requirements.
DVD videos that do not meet standard
requirements cannot be played.
■
About Sound
Q:
Can I play discs with "Dolby Digital EX"
printed?
A:
You can, as Dolby Digital EX is compatible
with Dolby Digital.
However, if you wish to obtain the original
effect, you need to connect the unit to a com-
patible amplifier or a receiver with a built-in
surround decoder or decoder, by using the
unit's digital output terminal. To do this, set
[Digital OUT] to "Stream/PCM" in the sound
setting screen of the unit.
Q:
Can I play discs with "DTS ES" printed?
A:
Yes you can.
However, if you wish to obtain the original
effect, you need to connect the unit to a DTS
ES enabled amplifier or a receiver with a
built-in surround decoder or decoder, by
using the unit's DVD digital output terminal.
To do this, set [Digital OUT] to "Stream/PCM"
in the sound setting screen of the unit.
Q:
What sort of disc has "THX" printed on it?
Can I play that disc on this unit?
A:
Yes you can.
"THX" is a name of an original division and
standard for high quality recording of pic-
tures/sounds or playback established by
Lucasfilm Ltd in the U.S. It designates the
discs and equipment that meet that standard,
but it does not designate a recording format
type.
Q:
When both MP3/WMA format and audio CD
format are recorded on a single CD, can I
play both of them?
A:
In that case, because the tracks have been
recorded with data CD format, the tracks on
the audio CD cannot be played back. You
can play back only the MP3/WMA format
tracks.
Q:
Dolby digital discs sometimes contain two
types of surround sounds; 5.1-channel
surround and Dolby surround. What is the
difference?
A:
Both are surround sound standards devel-
oped by Dolby Institute in the U.S. Dolby sur-
round is created by recording the surround
components (2ch) on top of the regular ana-
log stereo sounds (left/right), and then sepa-
rates and plays back the sounds using Dolby
surround and Dolby Pro Logic decoder.
With Dolby digital (5.1ch-surround), a maxi-
mum 6-channel system in total, which
includes the front left, the front right, the cen-
ter, the rear left, the rear right, and LFE (Low
Frequency effect: for lower sound signals
such as sub-woofers) can be digitalized,
compressed and independently recorded
before they are played back using Dolby Dig-
ital decoder.
Although it depends on how the sounds are
recorded, generally speaking, Dolby digital
produces better a sound field effect.

About Picture
Q:
I can see small mosaic-like patterns on the
screen of DVD videos or video CDs. Does
this mean there is something wrong with the
unit?
A:
This is something unique to digitally recorded
moving pictures (block noise) and that does
not mean there is something wrong with the
unit.
■
Others

Some discs do not respond to the operations
explained in this Users Manual.

tions on this unit, because of reasons such
as the contents creators' intentions or struc-
tural limitations.

Can I record DVD video contents onto a
videotape?
A:
Since most DVD contents are copy pro-
tected, you cannot record the contents to a
videotape.
Q:
Can I record with this unit?
