Hell of a log. It appears that NeroVison can successfully convert your files. I always save to a Hard Disk folder (you should then play them from the HD to make sure all is working right) and burn separately rather than direct to disc. Save to HD then open NeroExpress for the final burn and try burning at 8X. If in fact you can save NeroVision's output to your HD and NeroExpress still fails when burning grab ImgBurn and use the 'Build' function to create an ISO which can then be burned by ImgBurn. This will help determine if it's just a Nero problem. http://forum.imgburn.com/index.php?showtopic=1778 You might also want to set your main burner as Master (or if using CS hook up to the end IDE connector). Maybe just a change of media is all that is needed.
