Brasero disc burn error when checksum done

Using either of these two devices:

Samsung TSST Corp CDDVDW SH-S223L
or
lightscribe model DH-16A1L

with ubuntu 10.10 with all updates results in bad CD being
created with data files.

Did a

sudo chmod +x /usr/bin/wodim

and first disc was OK, but all after that are defective. I am willing
to run other tests, if necessary, to determine nature of problem.
Surely I'm not the only one having problems. Also, since whodim is
installed with regular install, should not cdrkiti-doc be installed for
info command?

Thanks in advance,

chuck
