there is no difference between drivers ( mine or AS )-

the only difference is that the active silicon dmg installs a quicktime driver for use with other quicktime applications-

the quicktime driver does not have good low latency performance- and should not be used- though it does work in catalyst.

those system commands you detailed - uninstall the quicktime driver-

Install the driver from the link on my website - this driver is written by Richard for Catalyst and differs from the 'standard' driver available from Active Silicon

Let me know if this solves the issue
