BD Ripper (3D Plus) BD to MP4 bad sound

[mark2112]

Hi there,
I'm trying to rip Avatar BD to MP4 @ 7.5gb output size but the sound comes out really weak. The picture is great. The sound details on the finished file are listed as.....

192kpbs
6 channel
48khz

Sorry if I'm a bit light on info, I'm new.

In the profile I usually increase the sound volume to 150%. I usually watch mp4 on my cellphone in the car (as a passenger). The road noise makes it hard to hear.
