My machine has been working fine for 5 months, and all of a sudden today, it decided to stop working.

I was watching a dvd and then it stalled at one scene, then resumed. I took the disc out, put it back it in and it will forever be in the disc loading screen.
I tried to put the same dvd onto another machine, it was working, and when I tried to load another dvd onto the avayon, it's not working.

Is my machine fried??
