I have been using nero since cd burners were released. If you are getting coasters, you are buying poor quality blank CDs or your IDE bus is too sluggish to run at the maximum speed your CD-R is reporting - use speed test to determine what the fastest safe speed is. Ideally you want DMA mode.
If you can move your CR-R to the 'Master' position on its own IDE channel, and the HDD you are copying from is also master on its own IDE channel, you are in top shape.
Another thing many people might not realize, and consider 'shuffling' is how the windows kernel interprets file dragging/dropping.
Say you have a list of 10 songs you want to move to a CD or a program such as Nero. Intuitively, you first click on the first file. Then, while holding shift, we click on the last file thus block-selecting the playlist.
We then drag this selection to the program of our choice.
Here is where the issue lies. Windows, having seen the last file as the one you most recently clicked on, will keep this on top of the stack. When you drag the list to the program and release the mouse button, it will put the last file in your list (song 10) in the first slot on the playlist/burn list.
To avoid this from happening, next time you are making a playlist for Nero, click on the last file of the CD first. Then hold down shift and click on the first file.
Now when you click and drag into a program, the first file will be song #1 as you intended it to be.
I hope this information helps someone. Computers can be quite picky when programmers do a job that is 'good enough for government work' as opposed to 'intelligent' code.
