2 problems with WinOnCd DVD edition

Hi,

I have 2 problems with winoncd.
The 1st one is that it keeps on crashing while browsing the file browser in winoncd. I am using windows XP and I installed the service pack for Winoncd.
I now close the file browser in winoncd and use my computer to drag files into Winoncd!

The second problem is that when I make a DVD music album from mp3 files , that the output quality is very poor! The music sounds very metalic. But there are no options in winoncd that can change the settings. The original mp3 file sounds much better.

Does anybody has some suggestions?
They advice winoncd, but it sucks if the sound quality is poor.
Have done the same thing with winoncd 5.0 onto a VCD and that went much better.
