Problem burning Audio cds, but I have no problem with others

[mmm_2000]

I use Nero 6.3.1.6 and an Emprex (sold at Fry's) which I had for about 2 years. The unit burns DVD+-R and RW at 4x and CDs at 52x CDR and 12x cdrw.
So far worked great with my Memorex and TDK DVDRW and also great with my FujiFilm DVDR and TDK,GQ CDRW.
I was able to write CD audio at any speed, but only the first 8-12 tracks (depending on the cd player) would play ok, the rest would be with all kind of skippings and noises. To solve the problem I was burning audio at 24x or 16x.
Now I tried again to burn audio tracks on some TDK CDR and I used 24x first (5-6 tracks would be wih noises/skipping) and even when I use only 8x(which is the slowest speed NERO lets me use) I still get problems on the last 2-3 tracks... Nero always burns the cds with no errors reported. I burned about 77mins of music.
WHY ? Is my burner dieing ?
It perfectly burns CDRW at 10x and DVDRW or R at 4x !
Any ideas ? And I did DAO.
Is there any way I could lower the burning speed to like 4x on audio cds ?
Thks and happy new year !

Could be your writer. Could also be Nero. Tried any other audio CD burner app? (CD Burner XP Pro?)

What are the source files?MP3,WMA,etc.
It's possible that Nero's decoder is adding the noise when converting to WAV,try converting the files to WAV first or as mats.hogberg said try another burn software.

I don't think the problem would come from decoding the mp3 or wma because, if I burn the audio cd at 24x, then the last maybe 5-6 songs will be with noise (like when you have a scratched cd). If I burn EXACTLY the same songs, exactly the same compilation if you want, at the lowest speed, 8x, then I would only get noise on the last 2 songs...
I'm going to try another burning software and I'll come back with the results.
Thanks for the tips !
