First of all, do you really mean CD, or DVD? Secondly, what do you mean by Progressive scan, are you talking about a standalone DVD player, and the use of component cables?
is this what ye are talking about,as that what some of the dvd players use.
Progressive scan
Progressive or non-interlaced scanning is any method for displaying, storing or transmitting moving images in which the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems.
Progressive scan is used in most CRTs used as computer monitors. It is also becoming increasingly common in high-end television equipment, which is often capable of performing deinterlacing so that interlaced video can still be viewed.
* Subjectively increased vertical resolution. The perceived vertical resolution of an interlaced image is usually equivalent to multiplying the active lines by about 0.6. This explains, for example, why HDTV standards such as 1080i (1920x1080, interlaced) in most cases deliver a quality equal to or slightly poorer than that of 720p (1280x720, progressive), despite containing far more lines of resolution.
* No flickering of narrow horizontal patterns
* Simpler video processing equipment
* Easier compression
Note: This system was originally known a 'sequential scanning' when it was used in the Baird 240 line television transmissions from Alexander Palace, England in 1936. It was also used in Baird's experimental transmissions using 30 lines in the 1920's.
How do you know they don't have Progresive scan? All DVDs will play through the component cables, unless your DVD player needs to be SETUP first for component cables.
