Mark, how do I do this? I've had a look but can't suss it out 
When you've got all the tracks that you want to burn in the relevant Nero window, right-click on each one in turn and choose 'Properties'. You'll see there's a setting to adjust the gap (it's 2 seconds by default) - just type in however long you want the gap to be and click 'Apply'. Be warned, however: you can't modify the very first track in the list of those to be burned. Why? Because the gap is actually added to the BEGINNING of a track, not the end. And Nero likes to stipulate the beginning of the first track to be burned is always 2-3 seconds. Also, if you want a gap of, say, 8 seconds between the end of one work and the start of the next, be sure to add those 8 seconds to the first track that begins the following work, not the last track that ends the preceeding one, if you get my meaning.
