Audio of dvd is too distorted

[killingfloor]

I have a dvd that has audio that is very distorted( must have been capture at too high of a level) and would like to be able to fix this issue. I have tried Dgindex to Demux Video and then I used goldwave to lower the levels. I have to save it as a wav, but when I go to use muxman or ifoedit the audio file is too large. Should I be saving the audio in another format or should I use another program? I have tried belight to convert the audio files as well. Thanks for any help.

to what format did you convert to with belight? ac3? did you try lower the audio bitrate?

Tried ac3 and when I went to use muxman there was no sound. Same with Tmpgenc dvd author program. I don't have the ac3 plugin for Tmpgenc dvd author though, so this might be a problem. The other problem is when I convert the wav file( after lowering the volume level in gold wave) into any other format the distorted audio returns. Tried lowering the bitrate, but it seems out of sync then. Still a newbie when it comes to this part of restructuring the dvd.
