Need some advice. My Lite-On burner has been working for me flawlessly for the past 9 months or so. Never had a coaster or any other problems to speak of. Yesterday, all of a sudden, I try backing up a movie with both Shrink and DVDFab and my encoding speed averaged 800kbps, where it typically ranges from 3.5Mbps and higher. Also, when I use Nero, Fab, Shrink or other relative software, my cpu usage fluctuates from 89-100%. Also, will not allow me to burn ISO image files. When I try, my buffer runs crazy. I tried reinstalling the drive, flashed it and reinstalled latest firmware. I've already bought a replacement burner, but just wanted to know what could be the problem and can it be salvaged? Any help is appreciated!
