The Catalyst 12.10 Driver is working in Powerdirector 11 and In Powerdirector 9, the only versions of Powerdirector I have installed on this computer.
It seems to have fixed the Hardware Acceleration feature. I only tried producing WMV 1280x720 at 8300 Kbps.
The output was error free.
That is the profile I use for uploading to Youtube.
