Ok, I managed to get the whole thing working. Here are the reason for the problems I observed:
1. Initially I used the wrong version of mkisofs to create iso images - sorry for that! 2. The -dummy option of cdrecord-prodvd and dvdrecord is not as "dummy" as one would think it is. I did my first tests with a DVD-R, but was using the wrong the mkisofs command to generate the image. The subsequent tests I made with a DVD+R - still using the wrong mkisofs. However, although I used the -dummy option the drive _did_ write to the DVD+R before it failed because of the wrong ISO format. As a consequence all further test with the correct ISO images failed as well. I ignored the warning about the possibility of the media being prerecorded because I consistently used the -dummy option (one also gets warnings about incorrect start sectors when burning CDRs...) As far as I can tell the -dummy option is working fine for DVD-R but not for the DVD+R media. I verified this by accidentally sacrificing yet another DVD+R. Anybody to confirm this behavior? In the description of the "driver" option the man page states the following: ... There are two special driver entries in the list: cdr_simul and dvd_simul. These driver entries are designed to make timing tests at any speed or timing tests for drives that do not support the -dummy option. ... Seemingly there exist drives that do not support the -dummy option. However, I am not sure whether the problem I observed is caused by the firmware of the drive or by the device driver not providing me an error message in case the enabling of -dummy mode fails. Thanks to everybody for their support!
