On the rig in my signature I have burned 4 DVD's at a time using 3 external DVD-RW drives and the internal drive from an image file loaded in Daemon Tools with Nero 9.0.9.4 by means of "Use multiple recorders" feature in Nero Burning ROM. So, yes, it can be done, but I can't tell you what resources the process(es) are taking up since I was using the laptop to to something else while recording was in progress (and I burned 200 DVD's using this method for my office. Don't ask how long it took but I finished 3 six-packs before it finished ). PS. Could some moderator please move this to the appropriate forum since this is not about Windows XP? Thanks!
