DISC COMPATIBILITY

Compatible Discs

Note: Not all discs are supported by this system. You may nd a
disc that will not play on this system, but works ne on other players.
Various manufacturers of discs change technology from time to time
which may create compatibility issues. This is not a probelm with the
unit and is not covered by warranty.
Most DVD and CD-Audio discs are compatible with the AV7800
system.
The unit can also play most CD-Recordable discs containing CD-Au-
dio, MP3 les, and JPEG images - but not all such discs. Since these
discs are usually made on home computers, there is no certica-
tion process ensuring that all such discs play on all players.

DVD Regions

When a DVD disc is created, it is encoded with a “Region number.”
The disc will only play on DVD players with the same Region number -
for instance, a Region 3 disc won’t play on a Region 1 player.
Region 1: U.S. and U.S. Territories, Canada
Region 2: Japan, Western Europe, Middle East, South Africa
Region 3: South Korea, Hong Kong, Taiwan, Southeast and East Asia
Region 4: New Zealand, Australia, Pacic Islands, Mexico, Central/
South America
Region 5: Russia and the former Soviet Union, Africa, Indian
subcontinent, North Korea
Region 6: China

Incompatible Discs

The following disc types are incompatible with the system:
· DVD-ROM/DVD-RAM/DVD+RAM discs.
· Most DVD-R/DVD-RW/DVD+R/DVD+RW discs.
· Some Photo CDs.
· CD-ROM data discs.
· BlueRay discs.
· CD-Audio discs made with certain copy protection methods.
· Any DVD with a different Region number than the unit.
· Any disc that does not meet DVD Forum standards.

Why the system doesn’t respond the same way to all discs

When a DVD disc is created, the creator has to dene how the disc
will operate when loaded into a DVD player. For instance, some discs
begin playing immediately, while other discs only display a menu and
require a menu selection to be made before playback will start.
The DVD standard also allows the maker of a DVD disc to disable
functions at certain times, such as Fast-Forward and Stop (which is
why you can’t skip past the copyright warning screen). If some DVD
feature temporarily isn’t working for you, usually the disc is preventing
the player from performing that function.

Discs that don’t properly load and play

Some CD and DVD discs, especially homemade discs which do not
have all the data needed to properly initialize all DVD players, may not
load and play properly. They may even create a state where the DVD
player will not eject the disc at all.
