Man, I wish I'd known that. After spending days messing up around with dvd-record (a closed-source extension of cdrecord), it turns out that burning DVDs under Linux really is easy. Just get growisofs and go:
growisofs -Z /dev/cdrom -R -J *And presto, you get a DVD containing all the files in the current directory. Once more, Linux isn't harder to use, it's just hard to find the Right Way to do things :) -----
