Hallo Thomas,I tried cdrecord_ProDVD. It does not give an error message. But the session does not seem to be closed properly: I can't mount the DVD, which to me is a bad sign.
The only thing I have not tried yet is a different manufacurer. The only shop in our village only sells one brand. That experiment has to wait until my girl-friend has time to help me get into town. I can't travel alone :(
