I would > appreciate any suggestions for improving this. I have encoutnered something similar. I don't always get coasters, but if I specify speed=24 the machine is almost completely not responsive for the whole operation, the buffer min fill always very low or 0, and the average burn speed ends up being about 16x. If I specify 16x, the machine is still fairly responsive, I never get a coaster, and the average burn speed is still 16x. I also wonder if anyone might know what is going on. The only difference between your machine and mine is that I have an AMD 2500+ CPU and am running kernel 2.6.8. -Roberto -- Roberto C. Sanchez http://familiasanchez.net/~sanchezr
