Here are more tips in keeping your DVD ROM�s in tip-top shape (despite running DVD marathons� ah, so familiar). Always store your DVD�s inside their cases when not in use. You don�t have to have an expensive entertainment system, you just have space for your DVD collection. Do not just leave them lying around for the cat to walk on. Although DVD�s are not as vulnerable to damage from extreme heat or cold as videotapes and floppies, just the same, keep those DVD�s at room temperature and away from direct sunlight (or in the direct path of the air flow of your AC).
