Yes there are two lasers, for dvd it's a 650nm pitch red laser and for blu ray it's a 405nm pitch violet laser.
I don't know if you have a laser issue though it's always worth cleaning them from time to time, now having said that i believe my firmware for the BD-83 is the same as your firmware...

You like to play dvd's too so i would avoid source direct.
Just re-read your post again, for blu ray playback you can use source direct, it will give you playback without any processing whatsoever, if the disc is 1080i i'd switch it off, as long as you don't want to use any of the internal...
