I've been reading about this meatallic noise. I have this same problem. I use DVD2SVCD ver 1.0.9 build 3. Besweet for the audio conversion.
It does everything perfect except the noise. From what i am reading the conversion to 44100 from 48000 is a bad thing.
What I want to know is how do you change it so BeSweet will convert to 48000 instead of 44100 without having to redo the entire process over again?
