DVD players with version 3.x firmware have a hidden loophole menu
that enables one to disable Macrovision copy protection, override
regional settings, as well as turning off CSS (a digital copy protection),
and changing audio dithering & muting settings.
first displayed, you are greeted with a message "you should not

[setup], [pause], , , 
If there is a disc in the drive, you must stop it first (i.e. press
[stop], then enter the sequence above).
player has firmware/decoder board DS4.1x, it is no longer possible
to access the loopholes menu in the way described above, and I doubt
if a new sequence exists.
through the firmware reveals that Shinco has left all the text from
the loophole menus intact, and fortunately the code for the loophole
menu also remains. As a result, patched versions of this firmware
have become available.
patched versions of this firmware the loopholes menu is displayed
as a sub-menu item in the main setup menu, so there is no need for
remote control codes!
have gone a step further and instead of removing/changing the remote
control hack code, they have removed the loophole menu data structures
so while the loophole text and code still remains, the menu cannot
the menu data structures have been removed, patching the firmware
is much harder, so as a result only Macrovision and Region settings
have been included in the patched version (the less important CCS,
Automute and Dither settings have been left out).
below sequence was published by Lik-Sang, but I've yet to hear it
work on any Shinco player. I rather suspect that it was published
in an attempt to sell more players (although it is possible that they
received a pre-production unit from Shinco on which the code worked):
a DVD is playing, press [setup] and turn
off the password, then exit the setup menu and press [stop]
twice, followed by [setup], and you can
enter the loopholes menu.
moment patched firmware can only be used if you have a suitable EPROM
programmer, and if the EPROM on your decoder board is mounted in a
socket. It is hoped that patched versions of the firmware will be
incorporated into update CDs for a hassle free upgrade, but this will
