I live in Hong Kong and need to play cd's from all regions

Countries around the world have their own REGIONS. If your DVD unit is for the American market then it will only read and play discs that are REGION 1 or REGION FREE. Anything else it will not. REGION 1 : United States, U.S. territories REGION 2 : Europe, Middle East, Egypt, Japan, South Africa, Swaziland, Lesotho, Greenland REGION 3 : Southeast Asia, REGION 4 : Mexico, Central America, South America, Australia, New Zealand, Oceania REGION 5 : India, Afghanistan, Ukraine, Belarus, Russia REGION 6 : People's Republic of China, Hong Kong
I believe you get the idea.

DVDs are encoded with a "Region Code" to allow studios to control release dates around the world. Hong Kong Region Code is 3, UK is 2. Your player will not play back Region 2 DVDs that you are purchasing or renting in UK. It will work fine with Region Code 3 DVDs I would bet.

Sorry to deliver the bad news.

Hi,you can not play all DVDs unless you have a ALL CODE DVD player..
Here is the detailed info..
Regards and thanks for rating me.
-----
DVD region codes are a DRM technique designed to allow motion picture studios to
control aspects of a release, including content, release date, and price,
according to the region. DVD video discs may be encoded with a region code
restricting the area of the world in which they can be played.
It is therefore this US Association that is responsible for the RPC system that
effectively divides the world into six regions for the purposes of controlling
and manipulating distribution within the global DVD market.
There are six different official regions and two informal variations.[citation
needed] DVD discs may use one code, a combination of codes (Multi-Region), most
codes (Region 0) or every code/no codes (Region All). The commercial DVD player
specification requires that a player to be sold in a given place not play discs
encoded for a different region; however, region-free DVD players are also
commercially available.In addition, many DVD players can be modified to be
region-free, allowing playback of all discs. Region code Area 0 Informal term meaning "worldwide". Region 0 is not an official setting; discs that bear the region 0 symbol either have no flag set or have region 1-6 flags set. 1 United States, Canada, Bermuda, U.S. territories 2 Europe (except Russia, Ukraine, and Belarus), Middle East, Egypt, Japan, South Africa, Swaziland, Lesotho, Greenland 3 Southeast Asia, South Korea, Republic of China (Taiwan), Hong Kong, Macau 4 Mexico, Central America, South America, Australia, New Zealand, Oceania 5 Afghanistan, Ukraine, Belarus, Russia, Africa (except Egypt, South Africa, Swaziland, and Lesotho), Central and South Asia, Mongolia, North Korea 6 People's Republic of China, Hong Kong 7 Reserved for future use (found in use on protected screener copies of MPAA-related DVDs and "media copies" of pre-releases in Asia) 8 International venues such as aircraft, cruise ships, etc. ALL Region ALL discs have all 8 flags set, allowing the disc to be played in any locale on any player.

To change your Region Code click Start- Computer - right click DVD Drive - Properties - Hardware Tab - Click on the DVD Drive on the list of hardware then click on Properties button - click on DVD Region Tab - choose your country then click ok button - click apply button then ok on the previous window - restart computer.

Note: Region Codes can only be change up to 5 times.

RC means REGION CODE - Depending on the numbering, it means that your DVD will only play in countries designated by the code.

Example

RC 1 means Region Code 1...... This disc will play in dvd players in Canada, United States, U.S Territories , Bermuda.

RC 2 = Western Europe, incl. United Kingdom, and Central Europe; Western Asia; including Iran, Israel and Turkey, Egypt; Japan, South Africa, Swaziland, Lesotho; French overseas territories

DVD video discs may be encoded with a region code restricting the area of the world in which they can be played. Discs without region coding are called all region or region 0 discs.
The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region (region 0 discs are not restricted). The purpose of this is to allow motion picture studios to control aspects of a release, including content, release date, and, especially, price, according to the region. Many DVD players are or can be modified to be region-free, allowing playback of all discs.Region 1 Players/DVDs include: Canada, United States, US Territories, and Bermuda. See below:
