Michael, > Can you burn 52x with cdrecord? Not as far as I know/knew. I think the CD-burn speed is the middle of the three figures (52x24x52), and the first is the CD-read speed, but I don't know what the third figure is. > No. OPC is done to determine the burning power of the laser in your > CD writer. It has nothing to do with the rest of your computer. Thank you for explaining that. I'm wiser now :-) Jonathan
