I know the maximum capacity of a CDR is of 700 MB. But ive seen pages talk about overburning. What I don´t understand is if it is possible to do this in any type of data or just for audio cds. I tried to overburn using NEro by selecting it in advanced properties but when I start writing it imediately said that there wasnt enough disk space and that I should insert a media with more space. I also brough a cdr which said it had a 90 minute capacity or 800ish MB. But nero only detects it as an 80 minute disk. What do I need to do to burn these types of disks?
