Nero 97mins to 99mi cd-r. Files end up corrupt.

[mustaneekeri]

Im using Nero (5.5.5.1) to overburn approx. 97:40mins of data to a 99min cd-r. The burn succeeds but few of the files end up corrupted (There are one big 850Mb file and few small files), end part of the large 850Mb file is unreadable. Shouldn't it fit on the CD? What settings should i use CD Mode? Should i finalize the cd or not? What other settings?
