well.....sounds close to whats happening, but when i start my xbox up with the mod enabled i get the normal ms screen and the dvd doesnt open automatically, but it will open manually......i got to thinking and doing some more reading and figure i may need to clean the d0 point, by lightly scraping it......not sure if it will work, but it might as long as im careful about doing it......not unless someone else knows a way to fix it without going that far.
