I don't know the answer, but the reason the Jeronimo doesn't play back DVDs isn't that there's a conflict, it's that the Apple DVD Player needs certain hardware (i.e. display cards) to run. It isn't a software-only player, and I was told that for potential DVD piracy reasons, Appian wasn't able to get the info from Apple to make it work with the J2000. My guess is that this has nothing to do with burning DVDs. But if you run into problems, the days of $800 cards being necessary to run two monitors are long gone. ATI Radeon 7000 cards sell for a little over $100, and they're actually quite a bit snappier than the Jeronimo.
