I have a LG gce-8400b OEM version from dell, it refuses to overburn, although nero said it support overburn. I follow the instruction in setting the preference so that it will do disc at once overburn, but it stopped immidately before the real burn process and asked for a larger cdr. I even trick Wincdr by build a 703M iso, Wincdr burn it until 99%(702M?) and stopped with a error. Is the OEM version of GCE-8400b different from the retail version, can it do overburn. My system is P4 with xp.
