I was going to stay out of this, but oh well.....
TYT, just because there are quite a few of us that do not like Nero Burning Rom does not mean you have to take offense or be upset about it. It is beginning to sound like you work for Ahead.
Not everyone agrees here and you will find opinions on both sides of every subject. If you feel you are right about Nero and you have no problems with it, good for you. But just because Nero works for you does not mean it works for everyone.
Trying to verify and recreate Nero's problems is not always easy. There is a great deal to take into account. What hardware and software you are using, what settings and speeds, and most importantly..... what you are trying to burn. In you own words you only burn "data cds, or mp3 -> audio cds." Nero in most builds will work fine with these, it's when you try different types of images that Nero becomes a problem.
As Roady suggested search this Forum and I suggest other CDR forums as well. You will discover a great many Nero detractors as well. Most of them are ex-Nero users.
Now, I used to love Nero Burning Rom. It was by far my favorite burning proggie. But when I started burning more advanced images, was where I began to run into troubles. Here are two of my pet peeves with it (there are more but this is already a novel).
1) Nero releases builds that are extreemly buggy far to often. It seems like they would rather have the public be there beta testers. Once all the bugs are verified, they fix them and release a more stable build. There has been a great deal of speculations as to why, but Nero builds prior to version 5.5 were far better and less buggy. I know some peeps who use Nero 5.0 for this specific problem.
2) Nero has a poor image interpreter. If you burn a lot of ISOs, BINs & CUEs (like Moi), you will find that Nero is notorious for getting it wrong.....leaving you with a coaster. Granted, Nero is getting better in this department, but the problem still exists.
Just relax and take the opinions in stride, but there is no reason to be upset about it
