i have an intel system and when i burn dvds it never seems to affect my cpu temps much maybe a couple of degress if that. i would try to get my temps down before burning any more dvds cause thats pretty hot for an intel processor. what heatsink/fan combo are you using? maybe you might want to upgrade to a better setup.
