Comment 27 for bug 149076

I have the same/similar problem and I DO have 2 drives (the second/slave one is my CD writable one).

I had a similar problem in Gutsy but upon freshly installing Hardy I could burn iso's easily. The problem seems to have happened after an update.

RLIMIT_MEMLOCK...is that part of the problem? What does it mean?

My wodim output:

wodim: No write mode specified.
wodim: Asuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.
wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK limits.Device was not specified. Trying to find an appropriate drive...
