Most DVD players have 2 or 3 video and 3 audio hook-up options.
The various options are rated. Always try to achieve the best recommended option from the list.
Always choose a decent cable

Video

A TV/movie camera outputs the video signal in RGB.
RGB stands for Red, Green, Blue
YPbPr (or YCbCr) is known as Component Video.
- Y - the black and white information.
- PbPr - bandwidth reduced colour difference information, mathematically derived from the original RGB signal.
A DVD disc is recorded with Component Video signal in digital format. Hence Component Video is the best format to display a DVD on a TV. This format is common in US and Japan.
Most European/Asian/Australian DVD players converts and output the signal into RGB, without any noticable effects on video quality.
Although the output terminals of Component Video and RGB may looks the same, usually , the two formats are not compatible.
Most DVD players may also down-converting the origianl Component Video signal into a more suitable formats, such as S-Video, Composite Video to suit the current generation of consumer display devices.
1. Component Video - with Progressive Scan (The best )
  - Labelled as: Probably Progressive Video/YUV, PS
  - Output progressive scan YUV Component Video in the form of 3 BNC or RCA connectors.
  - Connect to the 3 video inputs of a progressive-scan line multiplier or a progressive-scan TV. Toshiba's version is called ColorStream PRO.
  - This format preserves the progressive nature of most 24-frame movie discs, providing a film-like, flicker-free image with higher vertical resolution and smoother motion.
2. Component Video / RGB (Very good )
  - Labelled as: Either RGB or YUV, YPbPr, YCbCr or Y/B-Y/R-Y.
  - Note: RGB (European) and YUV (US) are non-compatible variants of component video. A not so affordable transcoder is needed to link up the YUV player and RGB equipment.
3. S-video (Good )
  - Labelled as: Either Y/C, S-Video, S-VHS or AV1/2/3 (need to check via set-up menu).
  - Almost all players have s-video output. Connect either directly to a TV or to an AV receiver that can switch s-video.
  - S-Video keeps the origianl Y information, but combines the Pb and Pr into a single colour signal (C).
4. Composite video (Acceptable )
  - Labelled as: Either video, CVBS, composite, or baseband. Usually in yellow colour.
  - All DVD players have standard RCA (Cinch) baseband video connectors. Connect either directly to a TV or to an AV receiver.
  - Composite Video combines Y and PbPr into a single video signal.
5. RF video (Not recommended )
  - Labelled as: Coaxial, RF
  - Hardly any players have RF video output
  - Should only be used for older televisions.
  - Only output in mono audio, even on stereo TVs.
Audio
1. Digital audio (The best )
  
  Labelled as: Digital Out/PCM Bitstream [Coaxial, Optical]
  - Almost all DVD players have digital audio outputs.
  - There is no noticeable different in quality between the Phono and Optical output.
  - Through this output, comes one of the following:
    - DTS
    - Dolby Digital (AC3)
    - MPEG2
    - PCM audio (including PCM from CDs)
  - For Dolby Digital, DTS, or MPEG-2, the appropriate decoder is required in the AV receiver or as a separate audio processor.
  - For PCM through this output, a digital receiver or a DAC (Digital Audio Converter) is required.
  - DTS DVD discs require a player with the "DTS Out" mark
  - Connect a video phono cable(!) or an optical cable to the AV receiver/decoder
  - Depends on which player, the output format (DTS/Dolby Digital/MPEG and PCM) can be one of the following:
    - Separate connectors for each audio format
    - Select through a switch on the rear panel
    - Select through on-sreen set-up menu
2. Component analogue audio (Very good )
  - Labelled as: 5.1 CH, Surround
  - Only players with built-in Dolby Digital or DTS decoders can provide this output. On our website, such players are marked by these animated icons.
  - As a general rule: built-in internal decoders are normally slightly inferior than its external counterparts.
  - A receiver/amplifier with 6 inputs is required.
  - Most players with internal decoders also provide the options of outputting digital audio via Option 1 above.
3. Stereo/surround analogue audio (Good )
  - Labelled as: Either [Phono] Audio, Stereo, Left/Right or [Scart] AV
  - All DVD players include two RCA connectors for stereo output.
  - Any disc with Dolby Digital or MPEG-2 audio will automatically be decoded and down-mixed to Dolby Surround output for connection to a regular stereo system or a Dolby Surround/Pro Logic system.
  - Connect to either an AV receiver, amplifier, or TV.
4. RF digital audio (Laser Disc player only )
  - Combination LD/DVD players use RF to output Dolby Digital audio from laserdiscs.
  - Connect a coaxial cable to the Dolby Digital RF input of the receiver/processor.
  - Note: digital audio from DVDs does not come out of the RF output, it comes out of the optical/coax outputs. Analogue audio from LDs will come out the stereo connectors, so 3 separate audio hook-ups are required to cover all variations.
