I previously posted this (http://forum.cyberlink.com/forum/posts/list/30765.page#168892) but received no ongoing response. Maybe I did it the wrong way.

In a nutshell: I cannot effectively render (produce) any of the movies I edit, the process takes forever. Last night I tried to produce a 43 minute MPEG 2 movie and after 14 hours only 23% was produced (screenshots of the production progress and settings screens are attached). I have tried AVI, MPEG-4 and MOV with the same result. WMV was reasonably quick and created a watchable movie but bizarrely it was in 4:3 while the project is 16:9 and created a movie that was only 23 minutes long.

I have an Asus S56C notebook Intel i7 running windows 8.1 64 bit and 4GB RAM with an nvidia Geoforce GT 635M with 2GB dedicated RAM (see all specs in attached DxDiag file). I have aplied all patches to PD11 and all driver updates. I would have thought that this system should be able to handle this, hope I am not wrong!

I am running Power Director Ultra 11.0.0.3625 Serial Number VDE131223-01

Anti-Virus: Windows Defender (for 8.1)
Codec: CamStudio Lossless Codec v 1.5
Other Video Editing: None
Burning: Windows
Background Processes: I've tried PD with everything that is not essential shut down, no luck.
I cannot see a 64bit button on dxdiag.

I have un-installed/reinstalled PD 11 twice.

From other responses on this issue on the forum I tried to roll back the nvidia driver 301.42 but got the error message it was not compatible with my system.

I would really appreciate any help you can give., it is quite urgent
