It works fine with all other media but for any brand dvd+rw it goes straight to lead out and doesn't write the disc. Any ideas?
thanks

If you are using a built-in superdrive and your Mac is a few years old then the issue is that your drive doesn't support writing to +R or +RW media. You can check the drive's media compatibility by launching System Profiler and click disc burning. You should see which media are supported.
