Nero song intro clipped off + no sound

I’m using Nero to move songs from my KORG D-8 digital recorder to My Document files. I’m having two problems:

  1. After I burn those song files to CD using Nero, a couple seconds of the intro is always missing?? Could it be my settings in Nero??
  2. I can not hear my songs through my headphone while recording using Nero but I can it it great on the finished CD. I’ve re-set all the volume controls inside and outside Nero. Thanks.
