I am having this problem. It does seem to be medium specific.
I have just finished using a stack of Maxell discs with no problems. Those are gone and I am trying to use a stack of generic CD-R's I got at Target. I have used many of these generic discs before with no problem, maybe a year or so ago. But now with the current version of wodim they are not working. wodim -v -v -v speed=36 dev=/dev/sr0 -data /usr3/MP3/TMP/FlyLikeAnEagle_archive1.iso wodim: No write mode specified. wodim: Asuming -tao mode. wodim: Future versions of wodim may have different drive dependent defaults.
