They work OK for CDs but not for DVDs, at least not in current DVD players. I used the Avery "stomper" myself for DVD-Rs at first, and all was OK with my first DVD player, a relatively early Pioneer model that was built like a tank. But newer players had problems with them, usually somewhere after the halfway mark. Apparently to keep costs down, manufacturers started to use cheaper motors and control systems that can't handle unbalanced discs as well as earlier models could.
Fortunately my computer's DVD drive can copy most of my "unbalanced" discs, so I've been copying them to new discs labeled with Sharpies. These play fine in my newer players.
