Unpleasantly surprising, UDF filesystem is not supported by the kernel in 10.0. I have looked in /proc/filesystems k3b cannot write UDF filesystems to DVD. It says "cannot determine filesystem size". The udftools package is installed. Will 10.1 have UDF support? I can't check right now. UDF support is needed to write >2GB files to DVD.

Did you do "modprobe udf" ? ciao, Marcus

No. Since on 10.1b3 modprobe loads the module, I can assume that it does so on 10.0 as well. Anyway, the fact that k3b cannot create an UDF filesystem is not good. Might be unrelated to the kernel module, true, but a bug still. The system with 10.0 and DVD writer is in a different place, I can't check now. k3b creates an UDF filesystem when it detects files >2GB. Suppose that after modprobe udf, k3b works. It would be better, but not perfect. Loading the module automatically when needed would be perfect.

It would seem that mkisofs from 10.0 is the problem. I tried this on 10.1b3 and it works. I don't have a 10.0 system around right now. Can anyone test it and tell me if it works? dd if=/dev/urandom of=testfile bs=1M count=2200 mkisofs -rock -joliet -udf -o test.iso testfile dd if=/dev/urandom of=testfile bs=1M count=2200 2200+0 records in 2200+0 records out 2306867200 bytes (2.3 GB) copied, 671.307 seconds, 3.4 MB/s silviu_marin-caea@silviu:~> mkisofs -rock -joliet -udf -o test.iso testfile INFO: UTF-8 character encoding detected by locale settings.
