Doing dd from the DVD drive (NEC ND 3500AG/2.18) fails in a corrupt image afterwards, copying with 'cp' from a inserted CD triggers the shown error and box dies immediately:

Same happens when trying to to a 'tar ztf file.foo' (tar archive located
on DVD) -> FreeBSD dies and freezes immediately.
Does it panic or hang?
The DVD has errors on it which is why you can't read it.. Obviously the OS crashing when presented with bad media is not a good thing :)
The media is all right, I tried it on a FreeBSD 4.10 box and a Windows box (equipted with the
same DVD-RW drive, running on a different hardware platform).
Writing 'clear' images to the drive results in corrupted media, either DVD and/or CD-R/W.
