My LG LDA 730 just stopped reading any DVD. It was fine yesterday. I paused it, then stopped it for a while. After restarting it I wanted to speed up to the point where I stopped it, it froze. After several attempts it kept freezing at this point or near by. Today I tried again and all I get is a black screen and the little disc icon spinning for a while then it stops. These same discs work in my OPPO. Any suggestions.
