This is not an LM specific question, but LMers are so knowledgeable that I wanted to ask this question here to see if you had any ideas. I play with lots of distros, and typically they are CD-sized. However, I recently downloaded 2 that are DVD-sized and my computer won't boot from the DVD. I have no problems booting from a CD, and I have no problems playing CDs or DVDs through media players. Why would my computer not boot from a DVD? I am baffled!
