Of zoals Nero het zelf zegt:
Against the often expressed opinion many (but not all) CD recorders are able to burn audio tracks without the 2 seconds gap between the tracks. It's also untrue, that „disc at once" burning means, that a gap of zero seconds is written. The „disc at once" burn method just gives you the freedom to choose a gap length of your choice. Generally it's best to burn audio CDs using the „disc at once" method.
To modify the gap between audio tracks just double click a track in a Nero audio compilation. A dialog will pop up, which allows you to enter a pause length of your choice. If you would like to change gaps of several tracks, then select these tracks and choose the menu command Edit->Properties and enter the desired gap length. Note please, that the gap before the first track must be between 2 and 3 seconds with respect to the rainbow book definitions. It wouldn't make much sense to change this gap anyway, because nobody would be able to hear the difference.
Once you entered the gaps of your choice click on burn and leave the „disc at once" option checked (if your recorder supports DAO). If your recorder doesn't support DAO or variable gaps in TAO, then you will see a warning, telling you, that some of your gap settings couldn't be applied. In this case your recorder is unable to write the CD, that you want. The only thing you can do in this case is to carefully select your next CD recorder and make sure, that it's capable of DAO writing. Sorry.
Dus Alexander: leuk dat je het het domste vindt dat je ooit gehoord hebt, gelukkig denken de mensen die er blijkbaar verstand van hebben er anders over.
