Yeah I have had 3 laptop players go kaput on me. 2 before I even started this endeavor. Then the 3rd one went before I got to the BR discs. Would still read DVD's and CDs but not BR. Think they get out of alignment or something.
Also with BR you have to get all the license stuff 'just right' or it will not even play the disc at all.
So if you put the disc in and you can not even see the files on it it your pretty much screwed. I have found the player is usually just dead If anyone has a way to resurrect them I am all ears... I have 3 dead players at this point.
Though wall-o-movies is pretty sweet Way better than the 3 sony 400 disc changers I was using. The motor burned out on my second one of them and I figured it was time to get working on this... As sony does not make the dvd version anymore and the BR ver is 2000 bucks.
