Really?
First off, I have read review after review of 1-2G DVD+RW drives that show 2.4x
drives are CAV, at least performance-wise. I'll have to hit some engineering
specifications to confirm/deny.
Secondly, so maybe I assumed that 4x was CAV also, but maybe it's CLV instead?
I was under the impression that beyond CLV was impossible beyond 2x, but I could
be incorrect. Maybe these new 2G DVD-RW and 3G DVD+RW drives are capable of
higher CLV speeds.

I ran across it once, but haven't been able to run into it since.

Oh, thanx. My ignorance. I'll change that into a note for the Sony then.
