Menu
I have been doing some research. See this page http://home.t-online.de/home/0306855728-0001/CHindex1.html
The code that they list to see the secret version menu item seems to work (You can even set the region code to something else from the default of '0'). This leads me to suspect that this machine is in actual fact a CyberHome CH-DVD 402. They even have a MTK.BIN which I downloaded and made a CD as per the directions. I then put it in the DVD player and it said that it would update if I pushed 'play'. I then took the disk out as I did not want to possibly destroy my DVD player permanently! However, if anyone is desperate to remove the macrovision, you may want to try it. But THIS MAY MAKE YOUR DVD PLAYER TOTALLY UNUSABLE!!!!!! You have been warned, and I won't dare use the CD. From looking inside the player I can see a MediaTek chipset: MT1376GE and MT1336E. MediaTek software updates may work. But it is difficult to know which is the correct software version without possibly destroying a DVD player!

Each DVD-Video disc contains one or more region codes, denoting the areas of the world in which distribution and playback are intended. The commercial DVD player specification dictates that a player must only play discs that contain its region code. In theory, this allows the motion picture studios to control the various aspects of a release (including content, date and price.
