i got SVCD video transfered to DVD-Mpeg with almost perfect quality, but the audio i get is pretty hollow

i encode the audio by

1, use TMPG to demultiplex both CD's audio
2, use TMPG to join both mp2 files
3, use TMPG to resample the 44100 audio to 48000
4, multiplex the new audio file with the new m2v file


the sound i get seems to be hollow and shitty, anyone got any sugggestions on methods or programs to use. im guessing i should use toolame to encode the audio but all i need to do is resample it to 48000 not reencode it
