DirectCD - Burn Speed

Hi, DirectCD making corrupted CD-RW’s with Lite-On LTR-52246S drive, Media used:

Verbatim Ultra Speed CD-RW 74 (16x-24x).

This drive has SMART-BURN technology and DirectCD detects and burns at its full 24x speed for Mt.Rainier (which cause bad data), I need to throttle the Burn speed to 16x for error free CD, please help, maybe a registry key?

By the way: Ahead InCD also has this same issue cause there is no burn speed selector, I have emailed them also for a answer on their software but have yet to get reply.
