My less than faultless memory seems to recall reading an analysis once about the allocation of disc time for an audio recording. I don't know where it is now (assuming it wasn't a dream
), but this is somewhat the way that I recall it:
If your time measurement of the compilation is for the music content only, some other things may push it over the capacity limit.
First, there's the 2 second delay before the first track. Then there are the standard 2 second silences between tracks. Since there is only a 15 second difference between your rated disc capacity and the nominal compilation length (perhaps before silences), anything over 7 or 8 tracks might push the true length with silences inserted beyond the rated disc capacity. Anyway, for what it's worth that's the theory.
As far as the overburn prompt, is Nero already set up to overburn?
I just saw your latest post, and maybe it is a problem with Nero 126.96.36.199 if it worked with an earlier version of Nero. Nevertheless, it would be an interesting experiment to remove the silences between the audio tracks and see if the time was lowered to an acceptable limit.
