Scott,
an amazing piece of craftsmanship. Well done.
I also have a question regarding this matter. I use a playstation 2 ("slim" model) as a cd and dvd-player, but I get a lot of failures on startup (it works fine when the children use their games).
Could a device like you've made cure these problems ?
thanks, Jos
Probably not Jos, sorry. Your failures are likely more intrusive than the effects that trimming or a CD marking pens would help with. You can try marking the outside of a CD that commonly fails with a green permanent marker. If this seems to help you can try it with more CD's. I would guess that your problems lie in laser alignment however.
Good luck.
