Thought was DVD was done but 2 audio issues are holding me back

First issue is the audio for the video is just too low, i got the video from vhs and recorded it to a dvd. Then editied in sony vegas and raised the voulme as much as i could but its still too low.

Second the audio is about 2 seconds too fast. What the quickest way to fix this? I have tmpgenc and dvd author and sony vegas. I need to demultiplex the file? Take the audio and take off 2 seconds from the start? I downloaded virtualdubmod but when i try to open it is says im missing corona.dll. Downloaded ffmpeg to get the audio file but not sure what to do with it. Take the file edit it audacity and then put it as the audio file when authoring???

So now i demultiplex the files, im gonna open up the audio in audacity and minus some time from thestart. But i wont know if its exact until i multiplex them back together
