SOHW-1673S Problem(stops while writing to disk)

I burned a few disk today at 8x and the burner worked fine. Now all of a sudden while burn the buffer goes down to 8% and it just doesn’t move. What could be causing the problem?


try: 1. update to latest official firmware [could be a patched firmware that is causing the trouble]
2. another brand of dvd disc.
3. slower burn speed.
