DVD PLAYBACK

Using a DVD’s Menu

One of the unique features of the DVD
system is that it offers a producer the
opportunity to include a wide range of
features on a disc, including multiple-
language tracks; subtitles in a variety of
languages; special information such as
movie trailers and cast information; as
well as other customized information. In
addition, producers may divide a movie or
program into chapters that allow for quick
access to specific parts of the program.
These chapters may be accompanied by
thumbnail pictures of a scene from the
specific chapter to help you select the
desired spot on the disc.

When a disc is playing, press the

Disc

Menu Button

to pause the

playback and display the disc’s menu. As
there are no hard rules about style and
content for DVD menus, the way they
appear on the screen and the information
they contain will vary from one disc to
another. However, the following general
rules apply to most menus:

• The first menu that appears is the Main

Menu, and you may move through the
options with the

Navigation

⁄¤

‹ ›

Buttons

, as the disc’s

programming allows. The option selected
will typically be highlighted in a certain
color or inside an outline box.

• To select a highlighted option, which

may either play a portion of the disc or
move to a submenu, press the

Set

Button

Play Button

• On some discs, when you select the

DVD menu during the playback of a
movie, the disc will return to the point
in the program where the menu was
selected by offering a “Play Movie”
option. Press the

Set Button

Play Button

to resume

play. However, not all discs offer this
feature, and selecting the menu while
playing a movie may mean that you will
either have to go back to the beginning
of the program or the start of a chapter.
This feature is out of the control of the
CVR700, as it is set by the disc’s inter-
nal programming.

Important Notes on DVD
Playback

The sensitive CVPD50 plasma display
screen is vulnerable to “burn-in” if any
still image remains on screen for any
length of time. It doesn’t take very long
for an image to burn in, and it is impor-
tant to avoid leaving certain displays on
screen for more than a few minutes, as
“burn-in” cannot be repaired, and will not
be covered by your warranty. Therefore,
DO NOT leave DVD menu screens on dis-
play for more than a brief period of time
unless they contain movement. Either
begin play of the movie, or turn off the
system (especially the screen) after 5
minutes.

The CVR700 is capable of all the features
and options covered by the DVD standards.
However, it is up to the producer of a
DVD disc to decide which of those fea-
tures and functions are available on any
given disc. For that reason, not all discs
will function identically, and some discs
will not have many of the features of the
DVD system. For example, most current
DVD discs do not take advantage of the
multiple-angle feature. When you press
a button and the player displays the
“Feature Not Available” message, this is
an indication that the disc has not been
programmed for that feature, or that the
CVR700 is not capable of executing that
command on that disc in the current
mode.

In addition, it is common for the produc-
ers of DVD discs to block the use of cer-
tain functions during only some parts of a
disc. For example, many discs prohibit the
use of fast-play buttons or prohibit access
to the Chapter Menu display during the
playback of copyright notices, studio
logos, movie credits or trailers. The
appearance of the “Feature Not
Available” message, or the inability of
certain features to operate when the disc
itself has prohibited them, does not indi-
cate a problem with the CVR700, as these
features are outside of the unit’s control.

• Some DTS discs contain incorrect digi-

tal flags that may initially cause the
CVR700 to display incorrect information
on the available surround modes or
other features. This is the fault of the
disc author and not the CVR700, which
will correctly process the disc’s bit-
stream once it has been detected and
identified.

NOTES ON DVD-AUDIO DISCS:

• Some DVD-Audio discs contain two

menus, one used when the disc is
played on a DVD-Audio player, and a
DVD-Video menu used on older players
that do not recognize the DVD-Audio
format. You may view the DVD-Video
menu by turning off the CVR700’s DVD-
Audio capability temporarily, using the
DVD Setup menu (see Figure 31). You
may wish to do this in order to access
certain audio surround tracks, such as
Dolby Digital 5.1 or PCM on the disc.
When you have finished exploring the
DVD-Video capabilities of the disc,
remember to restore the CVR700’s
DVD-Audio capability.

• Some DVD-Audio discs do not permit

you to access the disc menu using the

Menu Button

. However,

pressing the

Title Button

or the

Audio Button

may provide menu

access. In addition, you may simply
place the disc in Stop mode and play
the tracks in order.

Zoom Feature

The CVR700’s advanced digital video pro-
cessing circuits include a Zoom feature
that allows you to enlarge the image for
closer examination of a particular part of
the picture. Four steps of enlargement are
available.

• To use the Zoom feature, press the

Zoom Button

while a disc is

playing or paused. Each press of the
button will increase the zoom-in effect.
When you have zoomed through all
four steps, the picture will return to
normal size.

• When in any of the Zoom modes, you

may use the

Navigation

⁄¤

‹ ›

Buttons

to navigate

around the frame.

• Some discs are created in a way that

prevents the Zoom feature from operat-
ing. In addition, the Zoom feature will
not operate on disc menus and may not
operate on subtitles.

• The Zoom function is not available for

VCD or JPEG discs.
