CDRWin wont write audio tracks under 4 secs?

[Rocco]

Hi guys.
Just got into this Cd writing lark.
I've backed up quite a few PSX and Music CDs using CDRWin, but just tried to backup SouthPark Rally (UK version), and it keeps telling me that because the disc contains an audio track less than 4 seconds long, its an illegal format?

Am i missing something obvious?

Cheers
