I use Nero 5.5.10.35 Enterprise Edition, and it changes the file names to uppercase and spaces to underscores (_), for example:

01 - When I Saw Her Standing There.mp3

is changed into:

01__WHEN_I_SAW_HER_STANDING_THERE.MP3

How can I avoid this?

Thanks

You may need to record using ISO level2 and not level1. Also, make sure Juliot check box is checked.
