    What is the deal with Scarts? Do they produce better picture quality? So what's below that Progressive Scan & following it is Component?

    So if I were to get a decent DVD Player, what kind of checklist should I draw up?

    A SCART is just a connector with 21 pins. Although there are standards, it can be used for any signal protocol that requires less than 21 connectors (they all do).

    So, for example (assuming the cable is of high enough quality that we can forget, for the moment, any issues that might arise with the proximity of the various connectors) an S-Video signal connected using a SCART plug is EXACTLY the same thing as an S-Video signal connected using an S-Video (DIN) plug.

    Benefits of SCART over other connectors:

    1) One plug rather than several
    - ease of use
    2) One of the pins carries a switching voltage that can tell a TV to switch itself to the AV channel, go widescreen etc.

    Disadvantages

    1) One plug rather than several
    - lack of flexibility can cause problems. EG if you want to route your video signal to a separate destination to your audio signal. Unwanted loopthrough effects. Poor quality connectors can give rise to crosstalk. etc etc
    2) One of the pins carries a switching voltage
    - doesn't always do what you want - maybe you dont WANT the TV to go to the AV channel automatically whenever you switch your DVD player on. It's often difficult to disable.

    To answer your question (which was partly about signal protocols rather than the type of plug used), you should seek both a TV or Projector AND a DVD player that can handle, in order of preference:

    1) Component Progressive Scan (best)
    2) Component Interlaced OR RGB (equal)
    3) S Video
    4) Composite Video
    5) RF (worst)

    But, for example, there is no point in buying a DVD that can do Component/Progressive if the TV won't handle it and you aren't going to buy a better TV in the future.
