Help with 2 of my games

After ripping the cdi files of 4x4 evolution and F1 formula racing. Each of those games had audio sessions shorter then 4 secs. Cdrwin and Fireburner wont let me burn audio sessions shorter then 4 secs. Does anyone know how to make them longer or even find a program that will let me burn under 4 secs...any help would be appreciated...my email is [email protected]
