Did you try right click/properties on a song for changing the pause? It works for me. Yep, I selected all the tracks and set them all to 0 seconds, but when it is starting to burn it gives me the error that it can only be between 2-3 seconds between tracks.
Is it a trial version or full? It is the full version.
I'm pretty sure mine is a Benq (looks are identical, except for some of the labelling)

You can not adjust the pause between tracks (songs) only when recording in TAO (track at once mode). Hmm, but isn't TAO lower quality? Nero claims that DAO is the preferred method for burning high quality audio cds.
