Probably it isn't cdrecord's fault since a readcd -c2scan shows a perfect CD. Now I have disabled DMA for the Plextor drive and now these errors have gone. So it must be related to Plextor+Linux+DMA . On my private PC at home (a newer Plextor 48x) I cannot access the drive at all when DMA is enabled (even a simple 'mount' of an ISO filesystem hangs) and the kernel log tells about a DMA timeout error. (The kernel is a recent 2.4.23-rc?) Has anybody made similar experience and/or knows what to do? Is this a case for the Linux kernel mailing list?
