I'm running debian/unstable with a 2.6.8.1 kernel and growisofs 5.21.4.10.8-1. The machine has a Samsung TS-542A. growisofs works fine for DVD+RW media but refuses to do anything with DVD-R or DVD-RW media with a 'Wrong medium type' error.

This is formally impossible state, blank DVD-RW in Sequential mode with lead-out at less than 4.7GB. Was it written before? If yes, then you should know that Sequential mode requires blanking procedure to be applied before you can re-use media. Alternative is to format for Restricted Overwrite with dvd+rw-format -force in which case it will act more like DVD+RW. If media wasn't written before that it's simply not recognized by your firmware and you should either upgrade or switch to another media brand.
For the reference. I have received a problem report from another TS-H542A/TS03 user claiming that growisofs fails to start DVD+R recording with ":-( none Mode 1 track" error message. It's TSSTcorp firmware glitch which will be worked around in upcoming dvd+rw-tools update. A.
