Hello again! After some research, I've discovered the black magic needed to use multi-session and incremental writing on DVD. Unfortunately I have problems adding incremental support because of the actual architecture of cdrecord which is too CD oriented. The problems I have: 1. if I use -packet to specify packet/incremental write mode, cdrecord complains that TAO mode is not supported. 2. in DAO mode cdrecord incorrectly assume that the write address should be negative for pregap to be written. There is no pregap on DVD. And also no CUE Sheet to be sent. 3. cdrecord gets the number of the tracks on the disk and other information from TOC. On dvd the TOC is fabricated and these numbers are not valid.
The point is that I did not want to modify the cdrecord generic part in my first patch, but now I can't do that anymore. Otherwise the incremental writing and multi-session will not work. I really expect that this patch will be included in cdrecord since it will do something that dvdpro does not. Joerg, I wait for a nice answer from you this time.
