Nero 6 Audio level default

Hi I am new to the forum, so please excuse me if this topic is old hat.
I use Nero 6, with vision express 3, to edit and burn my DVD’s. Unfortunately the audio level defaults to 33 %. If I remember, I reset it to 100%, but often forget, resulting in a low audio level when watching a film.
Logically, there must be a way to make Vision Express 3 default to a 100% audio volume. Any one help please ???

I have received a reply from Nero support as below :-

Dear valued customer,

thank you for your email and your interest in our software.

It is possible to add 2 additional audio streams to your video file and so the default audio level was set to 33% so that the audio stream isn’t overdriven. Sorry that it isn’t possible to change the default settings for this.

Should you have any other request, please don’t hesitate to contact us again.

Best regards

Logically, there is a value set in the program, which can be altered. I would dearly love to get around this annoying feature, if anyone knows a way.
