Hi, i cannot say much about cdw. It may or may not be using my command line software xorriso or cdrskin. Rather not libburn directly, if i get http://cdw.sourceforge.net/ right.
K3B on DVD usually uses growisofs as backend. It might be possible to lure it into using cdrskin as alternative to cdrecord. > I have a problem with burning DVD iso-images. > [...] Burning CD iso-images works flawlessly. I understand it is about burning to DVD or CD media, not about the size of the images all burned to DVD. > The burn finishes without error but the verify stops with > error: cannot read track 0. Try to compare DVD content and image file by shell commands. First set two variables to your actual file addresses. E.g.: image="debian-8.1.0-amd64-netinst.iso" drive="/dev/sr0" Find out the size of the ISO image in blocks of 2048 bytes. The commands /sbin/isosize -d 2048 "$image" or expr $(ls -l "$image" | awk '{print $5}') / 2048 with the example image yield 126464 . Use this number to cut out the ISO image from the start of the medium content. E.g.: dd if="$drive" bs=2048 count=126464 | md5sum should yield 1a311f9afb68d6365211b13b4342c40b - and no error message. The run of md5sum on the image file md5sum "$image" should yield the same checksum with a different file name 1a311f9afb68d6365211b13b4342c40b debian-8.1.0-amd64-netinst.iso Of course, any other ISO image and its DVD should yield a totally different checksum of 32 characters. If both MD5 checksums match, then all is well. If not, then the copy on DVD is not trustworthy. > I cannot figure out against which package to file a bug report. > It is a hareware problem - it eludes me swiftly ... Let's see whether verification fails rigtheously or not. ------------------------------------------------------------ Next you could use a command line program for burning, in the hope to see error messages without frontend filter. E.g. growisofs -dvd-compat -Z "$drive"="$image" or xorriso -as cdrecord -v dev="$drive" "$image" Have a nice day :) Thomas -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
