I'm not sure what has changed.
Before all nine of my games played fine on my console. Now only four continue to play and the rest gives me an Unrecognized disc error.
In addition, when I try to play a DVD, the movie loads and the image shows on the TV, but the movie hangs every 1 to 3 seconds making it unwatchable.
If you would like more details, let me know. I'm also technical so I can open and make repairs if needed.
