Dvdspeedcontrol

In some cases, software-level DVDSpeedControl might be overridden by the drive's firmware. Some modern "Green" drives have built-in logic that slows them down automatically. Conversely, some high-performance drives require a (like those found at RPC1.org) to truly unlock speed limits or bypass region coding.

Unbalanced or slightly damaged discs can cause intense vibration at high speeds. Lowering the speed prevents the drive from shaking and protects the internal laser assembly . DVDSpeedControl

: Modern external USB DVD drives often have built-in firmware that overrides software speed controls. If DriveSpeed does not change the noise level, your hardware may not support manual speed overrides. In some cases
