now this is weird.... i just use the standard IDE interface for my
cdwriter...and i have an 060/50MHz. have you tried enabling the
parallel read/write option - and also, what speeds are you set up for
0 (maximum) or 1 etc? larger chunk sizes should be better as the machine
wont have to shift so many IO operations between buffer and device.

those wont work - you need the live! drivers...which'll be another 4 weeks
later ;-)
