I used to be able to burn my stuff onto cds using nero 6 express, however recently i tried to burn but failed miserably. It hangs at 3% and the log tells me of invalid write state and something about the speed and refuses to burn at all. I am using the same brand of cds and only 1 of the 50 cds can work. i uninstalled nero 6, clean it with the tools from nero.com and updated the latest patches and still got defeated by a program. My sister who uses Roxio is able to burn a couple of my cds successfully but i couldnt with Nero. (take note that i burned it before and only 1 worked) Much help is appreciated thanks

[Edit]: I cant use Roxio as i do not have an E drive. Is there another program similar to nero which allows me to burn cds or can my problem with nero be solved?
