What is your nVidia driver version?
Right click in any open area of the Windows desktop
Select NVIDIA Control Panel from the popup window
Select SYSTEM INFORMATION at the lower left corner
Driver version should be the 1st line in Details
I have a GTX285 using driver 296.10 and Win7
Have you tried a dlfferent driver on the Win8 computers?
Thank you for your answer.
The current driver is 320.49 from the 1st of June 2013.
The driver is inside nVidia GeForce Experience marked as "current" (in german: aktuell).
What I do not understand is, why the clips run properly f. ex in PowerDVD but not inside PremierePro.
Therefore I do not think that it is a problem with the codec oder nVidia drivers, but maybe with the integration in
Adobe Player. I already was looking for further information about the Adobe Player inside Premiere Pro, but did not find anything.
Thanks for your reply
