Another possibility, if you have the RAM, is to use the team(1) program (it's in the ports) to buffer the data as it goes to the burner. You basically put it into the pipeline between mkisofs and cdrecord, and it buffers up to 5MB in memory (default, adjustable). Of course, you've got to have enough RAM to not go into swap during the operation. It's a very nice program, and I've been told that, with enough memory (32-64MB), you can be running X11 and compiling programs while the CD is burning (this is with a 2X burner, though). -- Darryl Okahata darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
