heres how I burn with one big wav file
I use cool edit 2000 to mix my mp3's up to 80mins long, select mixdown all tracks and this generates one big wav file, save this somewhere. with nero create audio cd and load big wav file , click on the file and choose properties, you can now split the file back into individual tracks. BUT WHY, because you can then burn the tracks without any pause betwen tracks, highlight all the tracks in the list to burn and then right click , select properties and then you can change the pause option to 0 this gives you continuous playback from start to finish but still the ability to select the desired track
