I've got k3b 1.0.2. When I try to burn a DVD from an ISO image, it writes the DVD and reports success and ejects the DVD. But then, it can't reload it and the subsequent verify aborts as a result. This happens on two different machines and burners (one built in and the other USB). I haven't tried it with CDs yet, and I haven't tried it with a non-ISO-image burn. Here's the debugging output: System ----------------------- K3b Version: 1.0.2 KDE Version: 3.5.7 QT Version: 3.3.8 Kernel: 2.6.22-gentoo-r1 Devices ----------------------- ATAPI DVD LS 8X16X8X16 GCAB
