I know that the maximum data throughput on a device is a function of the radius and rotation speed, but why doe the disc speed (not write speed) change? In fact it changes when the write speed changes too. jpyeron AT phoenix /cygdrive/c/Documents and Settings/All Users/Desktop/video/target $ wodim-pipe -udf .
