Denon DVM-1815 5-Disc Progressive Scan DVD-Video Player
Consistently damages DVD
Plays adequately.  Excellent sound reproduction (a feature it shares with many players.)  The carousel however, consistently causes the discs inside to slide out of their position and to get caught above the rotating tray.  This had resulted in catastrophic damage to many DVD's and makes the player useless as a CD changer.  Additionally, to avoid damage I have had to load only 1 disc at a time and immediately remove it after viewing.  Also, not quite as good at playing discs with light scratches.  (the scratches it causes though are not light but very heavy usually).
