Does system performance differ between the various players?
No. Although there are various models of CD-i players, every CD-i disc will perform exactly the same in terms of system speed or audio and video quality on every CD-i system. The Green Book extensively specifies how and at what speed the audio and video data should be read from the disc and parsed trough the appropriate decoding ICs. Even if a faster CPU is used in a CD-i player (which is allowed by the Green Book, but so far never actually implemented in any CD-i player), system performance will only rise slightly because the realtime retreival of audio and video from a disc is not influenced by the processor. The seektime of the laser-unit in the CD player may, according to the Green Book, not be more that 3 seconds for a full stroke. It is possible for a CD-i player manufacturer to implement a CD drive with a faster seek time, but apart from getting faster to the desired data, also in this case the performance will not actually differ. Some CD-i players however are known to load the
