cleaned the laser and adjusted the white cog yet? dvd-key is a swapper and these tend to **** up your laser. I just put in a magic3 (yes yes i know, DMS3 on the way) in my console a week or so ago and it didn't play 90% of my SILVERS, don't even talk about my cd-r's .
Solution? Cleaned the lens, adjusted the DVD and CD pots (with a multimeter) and adjusted the white cog. Result? Perfect booting from start up (a little quirk in the magic series on V4 machines that allow them to boot from start up, i think).
