I have just replaced all my NEC PATA drives with NEC Sata drives. The difference: 100% failure rate versus 0%. This must be a kernel or a wodim issue and it has been hunting me for at least a year. One kernel will fix it, the next update will break it again. 2.6.24 and 25 are worse than ever, in fact. It used to be that only the checksum would fail but the cd or dvd would be OK.This time the iso does not even get burned properly. Changing burning speed does not work and neither does using different media or a different burning program (brasero, gnomebaker). Check the output of dmesg, it is almost bound to show optical drive related errors.
Edit: I believe that your PCLinux is using 2.6.22. Expect more fun when you upgrade to a more recent kernel.
