I have noticed that burning CD's or DVD's takes longer on Roxio Media creator 7 than it does on Nero 220.127.116.11.
For example to burn a 4.7Gb DVD takes ~13mins on Nero and ~15min on Roxio.
Is that expected? Perhaps I should do a Kprobe on both.
Different programs do the same things different ways. This can take more or less time than the other.
Also it could be simply that Nero gets up to the maximum writing speed quicker than Roxio does. Thus giving you a quicker burn.
