I've posted on a similar topic before. the short story is that i could not make the dvd/cdrom drive in the tibook work for audio extraction unless i used the ide-scsi package.
while that worked in the sense that cdparanoia could see the drive, system performance during cd ripping is terrible. the load average goes to about 5 and the mouse is completely unusable. the strange thing is that the X server and a few X clients are hogging the cpu during ripping, which just makes no sense. i had enabled ide-scsi on my desktop machine (G4/500 "agp graphics" with the DVD-ram drive) thinking that it was necessary, and had the same performance problems. i just rebooted without it and found that cdparanoia could find the drive and extract audio just fine in ATAPI mode, and that system performance was otherwise normal (aside from cdparanoia hogging the CPU :) so i tried the tibook again without ide-scsi and cdparanoia -vsQ reports (and yes there is a disc in the drive): 004: Unable to read table of contents header Unable to open disc. Is there an audio CD in the drive? this must be the original error i got which prompted me to try ide-scsi. so i have two questions for the lists now: 1) is the MATSHITA DVD-ROM SR-8187 in the tibook somehow just incompatible with the ide-cd driver? anyone know? 2) do other people experience the same bad system performance with ide-scsi during cd rips? i can only guess that there's something wrong with that driver that's passing a bunch of interrupts to the X server somehow, which is causing the X server to ask for redraws or something on all its clients. kernel is benh 2.4.3 (tibook) and benh-2.4.8-pre7 (g4/500), cdparanoia III release 9.8 ideas? thanks rob
