Hi,

I know this is going to be a relatively broad issue, but I'm getting rather frustrated with losing HWA in more and more setups, using PowerDirector 14.

First, it was 1920x1080 - any combination of framerates/bitrates/whatever

And just this morning, it now refuses to apply HWA to 1280x720 - again any framerate/bitrate - which is the resolution I switched to after 1920x1080 stopped being supported.

Last time, Cyberlink was putting the blame on Nvidia - but I'd not done anything to change settings, driver version or whatever else could be involved with Nvidia

This time, the problem just started out of nowhere - I updated Nvidia drivers (clean install) after the fact - and still nothing...

EDIT: I should add that it's MP4 H.264 - and, an interesting thing is that PDR is happy to apply HWA to 2048x1080...

Any ideas? Before commenting on specs/graphics card/etc, I want to re-emphasize that everything worked fine last night...

There could be many causes for this. A system restore to the time before this happened should fix it or reinstall the video driver. You may have had a crash with PD14 while trying to encode. If this is the case then see this post on how to fix it: http://forum.cyberlink.com/forum/posts/list/48900.page .

Thanks a bunch - worked a charm - turned out I had 3 values at 1, which after editing to 0, gave me all of them back - including the 1920x1080 When the difference in rendering time can be upwards 20 mins, it's frustrating not being able to use the HWA.

Thanks again
