I came across this today:

Basically, Yamaha Cd burners use a slightly different method of reducing jitter on burned CDs. According to the review, there was a noticable improvement in quality for low-quality CD players, but very little for high-end CD players... This makes a lot of sense, as the cheaper players would be more vulnerable to jitter...

And if you go to the next page, there's somthing even more intersting- they said that you can IMPROVE the sound of prerecorded CD's by ripping it (DAE) and then burning it using the anti jitter technology. SUpposedly the "High and low notes seem more marked and the stereo distribution more emphatic"... It does sound like many of the same description, without the audiophile terms, that you hear from those jitter reducing circuits... I can see how this would work (while the reviewer couldn't) as all timing errors originally on the CD are irrelevant when the CD is ripped and stored on the hard drive. WIth DAE, there also should be no bit-errors.... Then, when its reburned with anti-jitter circuity, it would be a bit-perfect copy, with all jitter removed....

Then again, jitter can still be added later in the transport/DAC...But still, this technology sounds very intersting...
