Linux DVD Player on a Bootable CD?

Kumar asks: "I'm trying to make a bootable Linux CD with nothing more than XFree86 4 and ogle to play DVDs. I'm trying to make it as simple as possible: boot the system, change the CD, hit 'play'. If anyone has attempted anything like this before I'd like to hear of their successes and/or any tips on achieving this goal." A Linux box set up like this might make a nice alternative to an expensive DVD player. Is anyone working on something like this?
