DiVX Progressive Scan

[rojash]

PAL is the standard video system used for TV in UK (and most of Europe) as opposed to NTSC which is used in USA.
DivX is a fairly recent encoding system for compressed video (like MP4).
Progressive scan means that for each frame of a movie, all the scan lines are available, as opposed to interlaced scan, which is the standard for broadcats TV.
Interlaced scan means that for each frame of a movie, only alternate lines are used, so frame one will refresh lines 1,3,5,7 etc, and frame 2 will refresh lines 2,4,6,8... This requires reduced bandwidth, but obviously is not such good quality.

just to clarify the divx bit of rojash's explanation: you can often download divx-encoded films, as they stay high quality, and you can fit a full film on one cd-r (about 700mb). if the dvd player states that it plays these, then any films you may have burnt to disc that use divx, would play on the player.
