I've got several mpeg2 files that I'd like to use to author a DVD with, but the sound is a little soft. I usually split the file into audio and video, resample the audio to 48 kHz and normalize (with ssrc) and then recombine the file back into a single .mpg file. I'd like to be able to do the resampling and normalization without having to split and recombine. I'm not sure there's any way to do this, but I thought I'd check.... is there?

Thanks!
