I've been burning 100's of dvds with no problem and all of a sudden i am getting tons of write errors. All I have done was move apartments and unhook and reset up my computer. I was using nero, but tried downloading other programs and had the same problems with them. it writes a lot of the dvd, but then gets an error midway through, not always at the same point. I have tried different media, different files, different programs, etc. This leads me to think it might be the burner. It is also having some problems reading dvds that it has never had before. It is an NEC 2500 and is only a few months old. Anyone have any suggestions. I included the log from nero below in cas esomething in there says something important, i can't understand it. Thanks!
