As for you, my friend, I appreciate your trying to help solve my issue. My computer is only a year old and runs on a Pentium D 830 and on XP. I've tried updating every relevant driver and firware I can think of. I did the reinstall and it did help so much as to allow the music disc creator to launch but my results were the same with the distorted audio (uncompressed PCM and AC3 formats). Why do my video dvds burn fine but my music dvds come out messed up?
Allright, since it doesn't appear to be your computer (You didn't list all computer specs, so I can't rule this out 100%), lets attempt this from another direction:
What are the source of the files?
If you downloaded them (legally), then there could be copy protection on them -- What happens if you try to burn them using whatever program you purchased them from (I.E. if you got them from ITunes, try ITunes' burner.)
How have you been testing the files?
Try playing them back on your computer, as opposed to a DVD player.
What extension were the files previous to burning?
If you start with crap quality, you end with crap quality.
What were the encoding settings? (I believe its File->Settings, or File->Project settings, or it may be in the actual burn dialogue box... I'm too lazy to look right now...) There should be a "best" option somewhere -- Use that, and make sure that you don't have too many files for the DVD disc -- Otherwise it will auto-compress them to fit.
Try burning those same files to a CDR (obviously you won't be able to burn all of them.

Just burn a few that came out poor), and play the CDR on your computer. See if the songs are still poor quality.
Also, I can't remember if there was a way to make appendable music CDs -- This might have been EMC 7... But make sure your not doing that.
