ALL ABOUT DVD COMPATIBILITY: Here at HKFlix we sell DVDs from around the globe. Some of these DVDs are by design not playable in normal USA DVD players or on normal USA TVs. We do not accept returns for player incompatibility! So be sure you understand these three important topics before purchasing DVDs from other countries! 1. REGION CODING Many DVDs are manufactured for sale within a specific country or territory. And for the purposes of DVDs, various territories of the world were divided up into "Regions" (see list below). For example, the following is a breakdown of how the Regions are distributed: REGION 0: Also called "all-region", no region limitations! REGION 1: U.S., Canada, U.S. Territories REGION 2: Japan, Europe, South Africa, and Middle East (including Egypt) REGION 3: Southeast Asia and East Asia (including Hong Kong) REGION 4: Australia, New Zealand, Pacific Islands, Central America, Mexico, South America, and the Caribbean REGION 5: Eastern Europe (Former Soviet Union), Indian subcontinent, Africa, North Korea, and Mongolia REGION 6: China Consequently, normal USA DVD players are built only to play Region 1 DVDs, and will not play DVDs from other Regions. There are two solutions to this problem: 1) you limit your purchases to DVDs from your own Region; or 2) you buy a special DVD player that can play DVDs from any Region. Clearly the second solution gives you the most options, which is why we offer a wide selection of Region-Free DVD Players for you to choose from. 2. PAL/NTSC FORMATTING In addition to Region Coding, you need to be aware of whether a DVD is PAL format or NTSC format. For example, the standard format in the USA is NTSC, and the standard format in Europe is PAL. In the USA most TVs and DVD players cannot display a PAL signal properly. Consequently, your best solution is again to purchase a special DVD player that can convert the PAL signal to NTSC before outputting it to your TV. Note that modern projectors and plasma displays often CAN display a PAL signal. If you know that your display is capable of displaying a PAL signal, you still need to make sure that your DVD player can play PAL formatted DVDs. We offer a wide selection of Region-Free DVD Players that can either 1) output a PAL Format signal to your PAL-compatible display, or 2) convert the PAL signal to NTSC before outputting it to your display. Select the one that's right for you. 3. THE SOLUTION! If you love movies, the only real solution is to buy a Region-Free DVD Player that plays DVDs from all the regions and outputs in the format (PAL or NTSC) that suits your display. Without a Region-Free DVD Player, your selection will be severely limited, and you will be missing out on all that the world of cinema has to offer. ALL ABOUT HVD COMPATIBILITY: High-Definition Versatile Disc is a format originated in China that uses different compression to attain 1080i native resolution using a standard DVD-9 red laser disc. This format is now obsolete, and the only player we know of that was confirmed to be able to play these discs was the NEUNEO/HELIOS HVD-2085. If you are in doubt of your playback equipment, or feel that HVDs might not serve your needs, please do not order HVDs. We do not accept returns for player incompatibility. ALL ABOUT BLU-RAY COMPATIBILITY: Sony's Blu-Ray (or "BD") format requires a blue laser to read data, allowing more data to fit on a disc. This allows for higher definition audio/video and/or additional content to be stored on a Blu-Ray Disc compared to a DVD. And just to make things fun, these Blu-Ray Discs have a separate set of only three "regions". The breakdown for the three Blu-Ray Disc regions is as follows: REGION 1 (A): North and South America, and East Asia, excluding China. REGION 2 (B): Europe and Africa REGION 3 (C): China, Russia, and all other countries ALL ABOUT HD-DVD COMPATIBILITY: Toshiba's High Definition DVD (or "HD-DVD") format requires a blue laser to read data, allowing more data to fit on a disc. This allows for higher definition audio/video and/or additional content to be stored on an HD-DVD Disc compared to a DVD. HD-DVDs do not utilize any type of Region Coding. As of early 2008, HD-DVDs are no longer in production, having lost the "format war" to Sony's Blu-Ray.
