My LG burner started turning out coasters after about 6 years and a couple of thousand burns. Fry’s had a sale on Asus DVD-RW for $20. It worked fine on one blank DVd and then started burning at dialup speeds. Took 15 minutes to burn a 1.5 Gb DVD-the old burner did it in just under 3 minutes. Finally swapped it out this morning and new one burns at 3 minutes. Nothing like having to shut the system down, open the case and replace something TWICE to make it work.
