Right now, I'm cross-backing up it's best NOT to use "GUI" interfaces for this. as always - doing it from command line is much easier when you learn. and - you ARE NOT forced to use ISO-9660 filesystem. in unix recorded DVD is just readonly disk, you can use any filesystem it supports. if you do this often and your DVD's don't need to be windoze-readable (which could be adventage sometimes) then: - create partitions of exactly 9180416 sectors (which is 2295104 2K sectors - exactly DVD size) - use newfs to create partition. for best results use options newfs -m 0 -b 32768 -f 4096 -i 524288 note that -i specify how much bytes is available per inode. more given=less inodes created and less space wasted, but you may run out of inodes storing small files. this example allows you to store about 8900 files. - mount it and record what you like as usual - unmount and use growisofs to record a disc. use that disc with mount -r /dev/cd0 /mountpoint
