I dont know for sure, but it appears that a lot of players out there max out at around 2700-2800 kb/sec ie at ~2x CD speed. It could be that the CD drive in these players cannot read at a higher speed or it could be a firmware limitation. In the case of philips 623 I mentioned above, I know it can read a CD-R at 4x or may be even faster as it plays a 6000kb/s mpeg2 file pretty smooth. Nevertheless it stammers with a 2000kb/s VCD. So I tend to think that player limitations are more often determined by the built-in software rather than the drive hardware. But I could be wrong as my Pioneer player is an old model -- may be it simply cant read CDs faster than ~2x. Sorry I dont know how to make these players handle higher bit rates.
